Myanmar government soldiers and ethnic Kokang rebels have been fighting for several months in the country's northeast, and Chinese officials have complained of several instances in which shells and airstrikes hit across the border.
The statement Myanmar's Defense Ministry issued late today did not mention any shells falling into China. It said government troops occupied major rebel outposts yesterday and today, using artillery attacks and airstrikes, and that at least 24 rebels had been killed.
Foreign Ministry spokeswoman Hua Chunying reiterated China's "strong dissatisfaction" and urged Myanmar to restore stability to the region "as soon as possible." Myanmar presidential spokesman Ye Htut said he could not confirm the incident, but he told The Associated Press that China should keep good control of its borders.
"If these countries want to prevent incidents like these, they should beef up border control and not allow rebel groups to operate in these areas," Ye Htut said.
