The Chinese government has taken issue with Myanmar after a bomb landed in China during armed clashes in Myanmar earlier this week.
Chinese Foreign Ministry Spokesperson Hong Lei.
"China has already lodged serious representations with Myanmar, requiring the latter to investigate the incident seriously and to take effective measures to avoid repetition of similar incidents. China hopes both sides of the conflicts exercise restraint to ease tension and solve the dispute through peace dialogue."
One bomb landed on the Chinese side of the border at about 4pm on Tuesday during clashes between Myanmar government forces and the Kachin Independence Army in northern Myanmar.
No casualty has been reported in China. It was the second time that bombs landed in China from Myanmar since the clashes erupted.
