BEIJING -- China has lodged a solemn representation to Myanmar after a Chinese person was injured by a landmine on the Chinese side of the border with Myanmar on Sunday, a Foreign Ministry spokesperson said Tuesday.

"The incident is under investigation," spokesperson Hua Chunying said at a regular news briefing. "China is gravely concerned and has lodged a solemn representation to Myanmar."

Hua urged Myanmar to take effective measures to avoid such incidents and prevent the conflict in northern Myanmar from spilling over the border to affect Chinese human and property security.
