Cambodian international landmine activist Tun Channareth, who was a co-recipient of the Nobel Peace Prize in 1997, has wrapped up a trip to the US, where he hoped to gather support for a petition for the US to ban the use of landmines and cluster munitions. In an interview with VOA Khmer, Tun Channareth, who lost his leg to a mine in 1982, said at least 156 other countries have signed the international treaty to ban landmines, despite the failure of the US, China and Russia to do so. Tun Channareth, a former soldier on the border who is now 51, was also awarded an honorary degree by Seattle University for his work to help landmine victims in Cambodia and his advocacy to have the weapons banned internationally
