On the last day of a summit reviewing the 1997 Ottowa Convention delegates were expected to adopt a declaration and a five-year action plan to expedite the abolition of devices that kill or maim around 40 people a day.

"We remain gravely troubled that anti-personnel mines continue to kill and maim, adding new victims to the hundreds of thousands of landmine survivors requiring life-long care," read the draft text of the Nairobi Declaration to be signed by the 144 countries that are party to the treaty.

"The presence of mines still blocks the return of displaced persons, hinders the achievement of the UN Millennium Development Goals that we have pledged to meet, and impedes states and people from building confidence between one another," the draft text said.

The treaty, which came into force in 1999, bans the production, use, trade and stockpiling of anti-personnel mines.

About 40 countries, including the United States, Russia and China are not party to the treaty although they comply with it to varying degrees.

"We call upon those states that have not joined our efforts, particularly those that possess vast stocks of anti-personnel mines or continue to use this insidious weapon, to adhere to the convention without delay," the draft said.

China made promising noises in this direction on Friday.

"We stand ready to further expand out cooperation with the States Parties to the Convention in order to contribute to early elimination of landmines," Liu Jieyi, China's head of arms control and disarmament told a plenary session of the summit.

The 2004 Landmine Monitor, prepared by the International Campaign to Ban Landmines (ICBL), says Georgia, Myanmar (Burma), Nepal and Russia have used mines since 2003, while the United States continues to use landmines in Korea.
