Mexican Foreign Minister Patricia Espinosa Cantellano called on the world to reinforce its nuclear disarmament commitment.
The minister made the call at a ceremony marking the 40th anniversary of the Tlatelolco treaty, which bans nuclear weapons in Latin America and the Caribbean.
The Treaty for the Prohibition of Nuclear Weapons in Latin America, better known as the Tlatelolco Treaty, was signed at Tlatelolco, Mexico, in 1967.
The treaty, aimed at establishing a nuclear weapons-free zone in the Western Hemisphere including all Latin America and the Caribbean, prohibits testing, use, manufacturing, production or acquisition of any nuclear weapons.
The signatory countries should remove the "interpretative actions" about the banning of nuclear weapons, the minister said, adding that Mexico calls on all nations to take more decisive actions in favor of nuclear disarmament.
The weapons of mass destruction, capable of killing millions of human beings, compromise peace and environment, the minister said.
"Reducing the poisonous effects these weapons create around them remains a top priority, and the message of the treaty remains valid."
Such disarmament is a fundamental part of Mexico's foreign policy and the treaty has proved to be one of the best tools in achieving such disarmament, Espinosa said.
Reiterating Mexico's "high profile" on the topic, the minister said Mexican President Felipe Calderon has emphasized the issue repeatedly in his international tours.
The ministry has organized a two-day seminar for scholars, experts and government officials at its office, and Nobuaki Tanaka, UN deputy secretary for disarmament affairs, will attend the event, according to the minister.
