Myanmar has accepted responsibility and apologised for bombs dropped on Chinese territory last month that killed five people, China's foreign ministry said yesterday. The incident happened during clashes between Myanmar government forces and a rebel group called the Myanmar National Democratic Alliance Army. Thousands of refugees have fled to China since fighting flared on the Myanmar side of the border. China was infuriated by the deaths in Yunnan province and warned of a "decisive" response if it happened again. Meeting his Myanmar counterpart Wunna Maung Lwin in Beijing yesterday, Foreign Minister Wang Yi said a joint team formed to look into the bombing had clearly ascertained what had happened. Wunna Maung Lwin accepted the team's finding that bombs from a Myanmar aircraft killed Chinese citizens, and extended his apologies and offered compensation, the ministry said. "The Myanmar side will go after and punish in accordance with the law those responsible, and will also strengthen internal controls to avoid such an incident happening again," the ministry added. It said Myanmar would work with China to ensure stability along their 2,000km border. The Myanmar National Democratic Alliance Army, led by ethnic Chinese commander Peng Jiasheng, was formed from remnants of the Communist Party of Burma, a powerful China-backed guerrilla force that battled the Myanmar government until it splintered in 1989. The group struck a truce with the government that lasted until 2009, when government troops took over their region in a conflict that pushed tens of thousands of refugees into Yunnan.
