China filed a complaint on Tuesday against Myanmar after a landmine explosion injured a Chinese citizen on the border between the two countries.

Hua Chunying, spokeswoman for the Chinese Foreign Ministry, did not say exactly where the incident occurred. Hua, however, said that the explosion happened Jan. 3 Sunday, and injured only one person.

The victim happens to be a Chinese boundary affairs worker who was conducting an investigation in the area.

This is the latest incident that has added tension to the already strained ties between both nations. China has been reportedly asking Myanmar to apply some effective measures that would contain or handle to conflict between the Myanmar military and armed ethnic rebel minorities.

"The Chinese side has,” explains spokeswoman Hua, “demanded that Myanmar take effective measures to avoid the future occurrence of a similar situation and prevent the conflict in north Myanmar.”

Hua said that this incident is considered by the Chinese Foreign Ministry to be a serious concern, and is currently undergoing investigation.

She added that China has asked Myanmar to give more effective efforts to ensuring “the security of Chinese people's lives and property,” as well as keeping peaceful situations in the border areas.

The border between China and Myanmar is a 2,000 kilometer-stretch of land consisting of remote and hard to reach areas. The Myanmar military has been fighting against several rebel groups, with at least two operating near the area that borders with China.

Due to the fighting that has transpired for years, thousands of Myanmar civilians have sought refuge on the Chinese side of the border.

Despite a ceasefire signed in 2012, landmines are still lying on the border grounds waiting for some unsuspecting victims.

Myanmar's landmines, according to the Diplomat, are made out of a plastic polymer making it hard to detect using metal detectors. The material itself also takes a long time to degrade, which makes these old mines highly dangerous.
