Ottawa Treaty

Implementation

Treaty terms

Besides ceasing the production and development of anti-personnel mines, a party to the treaty must destroy its stockpile of anti-personnel mines within four years, although it may retain a small number for training purposes (mine-clearance, detection, etc.). Within ten years after ratifying the treaty, the country should have cleared all of its mined areas. This is a difficult task for many countries, but at the annual meetings of the States Parties they may request an extension and assistance. The treaty also calls on States Parties to provide assistance to mine-affected persons in their own country and to provide assistance to other countries in meeting their treaty obligations.

The treaty covers only anti-personnel mines; it does not address mixed mines, anti-tank mines, remote-controlled claymore mines, anti-handling devices (booby traps), and other "static" explosive devices.

Destruction of stockpiles

Signatory nations have destroyed more than 48 million stockpiled mines since the treaty's entry into force on 1 March 1999. As of June 2017, 159 countries had completed the destruction of their stockpiles or declared that they did not possess stockpiles to destroy. Sri Lanka reported in September 2021 that they had finished destroying their stockpile.

Retention of landmines

Article 3 of the treaty permits countries to retain landmines for use in training in mine detection, mine clearance, or mine destruction techniques. 72 countries have taken this option. Of this group, 26 States Parties retain fewer than 1,000 mines. Only two have retained more than 10,000 mines: Turkey (15,100) and Bangladesh (12,500). A total of 83 States Parties have declared that they do not retain any antipersonnel mines, including 27 states that stockpiled antipersonnel mines in the past. Canada retains mines for training, and also continues to make and use the "C19 Detonated Weapon" in combat. The latter does not qualify as a landmine under the treaty because it is fired by a person and not by a pressure plate.

Landmine-free countries

Through 2015, 29 countries had cleared all known mined areas from their territory: Albania, Bhutan, Bulgaria, Burundi, Republic of the Congo, Costa Rica, Denmark, Djibouti, France, Gambia, Germany, Guinea-Bissau, Greece, Guatemala, Honduras, Hungary, Jordan, Malawi, Mozambique, Nicaragua, Nigeria, North Macedonia, Rwanda, Suriname, Swaziland, Tunisia, Uganda, and Venezuela. El Salvador finished clearing its landmines before joining the Treaty.

At the November–December 2009 Cartagena Summit for a Mine-Free World, Albania, Greece, Rwanda, and Zambia were also declared mine-free. On 2 December 2009, Rwanda was declared free of landmines. It followed a three-year campaign by 180 Rwandan soldiers, supervised by the Mine Awareness Trust and trained in Kenya, to remove over 9,000 mines laid in the country between 1990 and 1994. The soldiers checked and cleared 1.3 square km of land in twenty minefields. The official Cartagena Summit announcement came after the Rwandan Ministry of Defence's own announcement of the completion of the demining process on 29 November 2009. Under Article 5 of the Ottawa Treaty, Rwanda was requested to become mine-free by 1 December 2010.

On 18 June 2010, Nicaragua was declared free of landmines.

Two more countries became free of landmines in 2011. On 14 June 2011, Nepal was declared a landmine-free zone, making it the second country to be landmine-free in Asia. In December 2011, Burundi was declared landmine free.

On 5 December 2012 at the 12th Meeting of the States Parties, six states declared themselves landmine-free. These were the Republic of the Congo, Denmark, Gambia, Guinea-Bissau, Jordan, and Uganda.

On 17 September 2015, Mozambique was declared free of land mines after the last of some nearly 171,000 had been cleared over 20 years.

The last land mines in the Falkland Islands were removed by 2020.

Landmine and Cluster Munition Monitor

The Landmine and Cluster Munition Monitor ("the Monitor") is an initiative providing research for the ICBL and the Cluster Munition Coalition (CMC), and acting as their de facto monitoring regime.

As an initiative of ICBL which was founded in 1998 through Human Rights Watch, the Monitor gives monitoring on the humanitarian development and uses of landmines, cluster munitions, and explosive remnants of war (ERW). It provides reports on all aspects of the landmine, cluster munitions, and ERW issues. It issues annual report updates on all countries in the world, keeps an international network with experts, provides research findings for all mediums, and remains flexible to adapt its reports to any changes. The Monitor has earned respect with its transparency whose states must be provided under the relevant treaties for independent reporting. Its main audiences are not only governments, NGOs, and other international organizations, but also media, academics and the public.

States parties

The Convention gained 122 country signatures when it opened for signing on 3 December 1997 in Ottawa, Canada. Currently, there are 165 States Parties to the Treaty. Thirty-two countries have not signed the treaty. The states that have not signed the treaty includes a majority of the permanent members of the United Nations Security Council: China, the United States, and Russia. In 2014, the United States declared that it will abide by the terms of the Treaty, except for landmines used on the Korean Peninsula. South Korea, like North Korea, has not signed the treaty, believing the use of landmines to be crucial to the defense of their territory against the other.

Responses

Supportive

Pope Francis has described the Ottawa Process as an example of where the organisations of "civil society" are "capable of creating effective dynamics that the United Nations cannot".

Critical

Criticism from academics, security officials, and diplomats is based on both the political process and the substance. The campaign for what became the Ottawa Treaty was led by a group of powerful non-governmental organizations, and instead of working within existing multilateral frameworks, including the Conference on Disarmament, based at the UN compound in Geneva (the Palais des Nations), an ad hoc framework was created that detoured around existing intergovernmental processes. Critics alleged that this represented a challenge to the sovereignty and responsibility of nation states for the defense of their citizens.

Substantively, critics view the treaty as naive and idealistic, in attempting to erase the reality of security threats that lead armies and defense forces to rely on landmines for protection against invasion and terror attacks. As a result, ratification has been far from universal, and many of the states that do not currently intend to ratify the treaty possess large stockpiles of anti-personnel mines. So far 35 countries have not signed the treaty; nonsignatories include the United States, Russia, China, Myanmar, United Arab Emirates, Cuba, Egypt, India, Israel, and Iran.

Opponents of banning anti-personnel mines give several reasons, among them that mines are a cheap and therefore cost-effective area denial weapon. Opponents say that when used correctly, anti-personnel mines are defensive weapons that harm only attackers, unlike ranged weapons such as ballistic missiles that are most effective if used for preemptive attacks. Furthermore, opponents say that the psychological effect of mines increases the threshold to attack and thus reduces the risk of war.

The Ottawa Treaty does not cover all types of unexploded ordnance. Cluster bombs, for example, introduce the same problem as mines: unexploded bomblets can remain a hazard for civilians long after a conflict has ended. A separate Convention on Cluster Munitions was drafted in 2008 and was adopted and entered into force in 2010. As of February 2022, there are 110 state parties of the CCM. In theory, mines could be replaced by manually triggered Claymore mines, but this requires the posting of a sentry.

Opponents point out that the Ottawa Convention places no restriction whatsoever on anti-vehicle mines which kill civilians on tractors, on school buses, etc. The position of the United States is that the inhumane nature of landmines stems not from whether they are anti-personnel as opposed to anti-vehicle but from their persistence. The United States has unilaterally committed to never using persistent landmines of any kind, whether anti-personnel or anti-vehicle, which they say is a more comprehensive humanitarian measure than the Ottawa Convention. All US landmines now self-destruct in two days or less, in most cases four hours. While the self-destruct mechanism has never failed in more than 65,000 random tests, if self-destruct were to fail the mine will self-deactivate because its battery will run down in two weeks or less. That compares with persistent anti-vehicle mines which remain lethal for about 30 years and are legal under the Ottawa Convention.

Compliance

Little progress in actual reduction of mine usage has been achieved. In 2011, the number of landmines dispersed had increased since 2004, landmines being dispersed in Libya, Syria, and Myanmar.

Turkey reported that between 1957 and 1998, Turkish forces laid 615,419 antipersonnel mines along the Syrian border "to prevent illegal border crossings". These mines are killing Syrians stuck on the border or trying to cross near Kobanî. Turkey is required under the treaty to destroy all antipersonnel mines, but has missed deadlines. Human Rights Watch claims in its report that as of 18 November 2014, over 2,000 civilians were still in the Tel Shair corridor section of the mine belt because Turkey had been refusing entry for cars or livestock, and the refugees did not want to leave behind their belongings.

During the Russian invasion of Ukraine, Ukraine has become the first party of the treaty to violate it. In the war, Russia has also used landmines forbidden in the treaty, but it has not signed the treaty.

Withdrawals

The Ottawa Treaty's signatories have largely remained consistent until the Russian invasion of Ukraine, wherein several European signatories have withdrawn from the treaty.

Poland, Lithuania, Latvia, and Estonia

In Estonia, a group of 20 MPs in the Parliament of Estonia from the Conservative People's Party of Estonia, headed by the former Chief of Defence Ants Laaneots presented a bill to withdraw from the Ottawa Treaty on October 2022. This was however met with reluctance by the Estonian Ministry of Defence, whose spokesman Thomas Mell claimed that there's no indication that Estonia would need to reintroduce anti-personnel mines, and the bill was voted down by the parliament. After the United States approved transfers of anti-personnel landmines to Ukraine on 19 November 2024 and the renewed debate in the neighbouring Finland on 23 November 2024, the parliamentary National Defence Committee decided to reconsider the matter.

In December 2024, based on the military lessons from the Russian war against Ukraine, the outgoing Lithuanian Minister of National Defence initiated the debate on the withdrawal from the Ottawa Treaty.

On 18 March 2025, the defence ministers of Poland, Lithuania, Latvia and Estonia jointly announced their intention to leave the Ottawa Treaty. The governments have reasoned that anti-personnel mines are an important capability and that Russia is not a party to the treaty and would not hesitate to use such munitions in a conflict with NATO. Russia has been using such mines extensively during its invasion of Ukraine. Despite their intention to leave the Ottawa Treaty, the defence ministers emphasized their commitment to international humanitarian law.

On 16 April 2025, the Latvian parliament voted to withdraw from the Ottawa Treaty; the Lithuanian parliament voted to withdraw on 8 May 2025; and the Estonian parliament on 4 June 2025. The withdrawal will take effect in six months after the countries notify the United Nations and other treaty members, allowing them to stockpile and use anti-personnel landmines. On 25 June 2025 Polish Sejm voted 413/15/3 in favour of withdrawal from the treaty.

All three Baltic States notified the United Nations of withdrawal from the Ottawa Treaty in June 2025. It formally took effect on 27 December 2025. Poland's withdrawal took effect on 20 February 2026.

Finland

In Finland, the National Coalition Party and the Finns Party have proposed withdrawing from the treaty in 2014, Finland having entered the treaty just two years prior. The stance was supported by the Finnish Ministry of Defence report from 2003, which saw landmines as an effective weapon against a mechanised invasion force. Although no decisions were made, the political debates and public initiatives to withdraw continued in 2018 and especially in 2022, after the Russian invasion of Ukraine Debate sparked again after the new Finnish Chief of Defence Janne Jaakkola pushed for reconsideration of the policy on anti-personnel landmines on 23 November 2024, based on the new developments in the Russian invasion of Ukraine. Following Jaakkola's appeal, three new citizens' initiatives were started for the withdrawal from the Ottawa Treaty, and the matter quickly started a widespread public discussion with multiple political parties pledging support for withdrawal.

On 1 April 2025, the Finnish government announced its intention to leave the Ottawa Treaty. The Finnish parliament voted to withdraw from the convention on 19 June 2025. The instrument of withdrawal was presented to the United Nations on 10 July 2025 and the withdrawal took effect on 10 January 2026.

Ukraine

Ukraine signaled in 2014 that it might have to withdraw from the treaty due to military necessity. Ukraine stated that it "remains adherent to its international obligations and is ready to undertake all necessary measures to destroy anti-personnel mines in mined areas under its jurisdiction. However, this could be done only after [Ukraine] will regain control of the territory currently occupied by [Russia]."

Despite Ukraine having not officially withdrawn from the treaty, US president Joe Biden approved transfers of American anti-personnel landmines to Ukraine on 19 November 2024, eliciting criticism for the rejection of the treaty from human rights organisations such as Human Rights Watch and Amnesty International USA.

On 29 June 2025, Ukrainian President Volodymyr Zelenskyy signed a decree enacting the decision of the National Security and Defence Council of Ukraine to withdraw the country from the treaty.

United Nations General Assembly annual resolutions

A recurrent opportunity for States to indicate their support for the ban on antipersonnel mines is their vote on the annual UN General Assembly (UNGA) resolution calling for universalization and full implementation of the Mine Ban Treaty. UNGA Resolution 66/29, for example, was adopted on 2 December 2011 by a vote of 162 in favor, none opposed, and 18 abstentions. Of the 19 states not party that voted in support of Resolution 66/29, nine have voted in favor of every Mine Ban Treaty resolution since 1997 (Armenia, Bahrain, Finland, Georgia, Oman, Poland, Singapore, Sri Lanka, and the United Arab Emirates); 10 that consistently abstained or were absent previously now vote in favor (Azerbaijan, China, Kazakhstan, Kyrgyzstan, Lao PDR, Marshall Islands, Micronesia FS, Mongolia, Morocco, and Tonga). Somalia, now a State Party, was absent from the 2011 resolution, but has voted in favor in previous years.

Since the first UNGA resolution supporting the Mine Ban Treaty in 1997, the number of states voting in favor has ranged from a low of 139 in 1999 to a high of 165 in 2010. The number of states abstaining from supporting the resolution has ranged from a high of 23 in 2002 and 2003 to a low of 17 in 2010, 2005 and 2006. The group of states that could be described as most concerned about the security implications of the Mine Ban Treaty are the 15 states not party that have voted against consecutive resolutions since 1997: Cuba, Egypt, India, Iran, Israel, Libya (since 1998), Myanmar, North Korea (since 2007), Pakistan, Russia, South Korea, Syria, Uzbekistan (since 1999), the United States, and Vietnam (since 1998).

Key figures in the making of the treaty

Letter-writers and non-governmental organizations

The Ottawa Anti-Personnel Mines Treaty would not likely have been possible without the sustained effort of thousands of global citizens writing their elected officials in the lead up to the treaty's creation and signing in 1997. A small number of core groups mobilized on the landmines problem worked closely with a wider variety of NGOs, including churches, prominent children's and women's rights groups, disarmament and development groups, in order to produce concerted political pressure, as well as with the media to keep the issue in the forefront. Because of this unparalleled involvement of the global public, and their success in lobbying for this initiative, university political science and law departments frequently study the socio-historical initiatives that led to the Ottawa process, arguing it is a leading modern example of the power of peaceful democratic expression and a method for mobilization on disarmament issues or more broadly.

Jody Williams and The International Campaign to Ban Landmines

The organization the International Campaign to Ban Landmines and its founding coordinator, Jody Williams, were instrumental in the passage of the Ottawa Treaty, and for these efforts they jointly received the 1997 Nobel Peace Prize. However, since efforts to secure the treaty started over a decade before Williams involvement and the fact that the treaty was a joint effort of so many people from all over the world, including hundreds of influential political and private leaders, some felt that Williams should decline to personally benefit from the award of the 1997 Nobel Peace Prize. Williams herself has said she feels the organization deserved the award while she did not, and emphasized the collective nature of the movement; as the chair of a group of female Peace Prize recipients, she has used her status as a Peace Prize recipient to bring concerns of woman-led grassroots organizations to the attention of governments.

Werner Ehrlich

Available sources such as the study on the Ottawa Treaty made by Stuart Maslen and an article published by Werner Ehrlich in 1996 indicate that the key figure in the making of the Ottawa Treaty was the Austrian diplomat Werner Ehrlich, head of the Disarmament Unit at the Austrian Ministry for Foreign Affairs in 1995/96:

He initiated the process by making the first draft of the future Treaty in April 1996 and succeeded to get this project and the proposed unorthodox procedure – to negotiate this Convention outside the Conference on Disarmament (CD) – adopted by the Ottawa Conference in October 1996 – in spite of nearly universal opposition.

It was an uphill struggle. This proposal was understandably rejected by countries which see anti-personnel mines as essential for national defense. Consequently, they tried repeatedly to block the project or to steer it to a dead end in the CD.

The proposal was however also opposed by Countries and NGO's supporting a total ban, because of their conviction that practical measures would be more conducive to a total ban than a Convention, A view which was reflected in the "purpose" of the 1996 Ottawa Conference: "to catalyze practical efforts to move toward a ban and to create partnerships essential to building the necessary political will to achieve a global ban on AP mines." But this meant in fact, that a total ban was postponed to a remote future: until practical efforts may have convinced one day Countries depending on APMs for their defense, that APMs are useless or counterproductive.

The approach of Werner Ehrlich was different:

It was essential to delegitimize as soon as possible any use of APMs by the adoption of an instrument of international law on a total ban of APMs, because it would not only bind the Parties to the convention but would also have at least a moral effect on Countries not Parties by clearly contradicting the idea that the use of APMs is legal.

It was also essential to elaborate this Treaty in a free standing negotiating process outside the Conference on Disarmament (CD), as there mine-affected Countries not Members of the CD would be excluded and opponents of a total ban could block the project immediately, e. g. simply by denying consensus to put it on the agenda.

At the Ottawa Conference in October 1996 Ehrlich defended the project of a Total Ban Convention, against opponents of a total ban as well as even against leading humanitarian organizations such as the International Committee of the Red Cross (ICRC) and the International Campaign to Ban Landmines (ICBL), which at the beginning saw the project as premature, as detraction or even as a waste of time. He succeeded finally against all odds – due in particular to the inspired and timely support of the Canadian Minister of Foreign Affairs, Lloyd Axworthy – to get his project indorsed by the Conference: Austria was tasked to draft the text for the negotiations which were to be held – as proposed – in a free standing negotiating process, a procedure later called the "Ottawa Process".

His third and final draft before leaving disarmament at the end of 1996 to become Austria's Ambassador to the Islamic Republic of Iran was known as the "First Austrian Draft" and served as the basis for the following negotiations leading to the adoption of the Mine Ban Treaty in December 1997

Canada's Mine Action

Mines Action Canada grew out of the efforts of Canadian non-governmental agencies concerned about the rapidly spreading impact of landmines and cluster munitions. The group was successful in garnering positive Canadian government attention to the call for a ban by mobilizing Canadians to demand action. By 1996, sustained and growing citizen action led Minister Axworthy of the Canadian Department of Foreign Affairs and International Trade to collaborate with Mines Action Canada and the International Campaign to Ban Landmines. This in turn led to the Government of Canada challenging other countries to negotiate and sign a treaty banning ban landmines within one year. This call to action led directly to the signing of the "Convention on the Prohibition on the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction" commonly known as the 'mine ban treaty' one year later in December 1997. Mines Action Canada was hosted by Physicians for Global Survival, chaired by Valerie Warmington and coordinated by Celina Tuttle from the coalition's inception until after the treaty was signed.

Diana, Princess of Wales

Once in the final stages leading into the treaty, the Ottawa Treaty was ardently championed by Diana, Princess of Wales. In January 1997, she visited Angola and walked near a minefield to dramatize its dangers. In January 1997, Angola's population was approximately 10 million and had about 10–20 million land mines in place from its civil war. In August 1997, she visited Bosnia with the Landmine Survivors Network. Her work with landmines focused on the injuries and deaths inflicted on children. Her death a few weeks later propelled the cause on the world stage and, as reported by Time magazine in their September 1997 edition, "After her death, the treaty... took on the luster of a humanitarian memorial to Diana and her cause." When the Second Reading of the Landmines Bill took place in 1998 in the British House of Commons, Foreign Secretary Robin Cook praised Diana and paid tribute to her work on landmines.

Lloyd Axworthy

In his Canadian Foreign Affairs portfolio (1996–2000), Lloyd Axworthy became internationally known (and criticized in some quarters) for his advancement of the concept of human security and including the Ottawa Treaty, and the creation of the International Criminal Court.

Bobby Muller

Robert O. (Bobby) Muller (born 1946) is an American peace advocate. He participated in the Vietnam War as a young soldier, and after returning from Vietnam, Muller began to work for veterans' rights and became a peace activist. Since then, Muller founded Vietnam Veterans of America (VVA) in 1978 and Vietnam Veterans of America Foundation (VVAF) in 1980. The VVAF co-founded the International Campaign to Ban Landmines, which won a 1997 Nobel Peace Prize.
