The extent of mine contamination remaining in the People’s Republic of China is not known.

In the 1990s, the United States (US) reported that China had emplaced mines along its borders with India, the Russian Federation, and Vietnam.[1] China’s military estimated that around two million mines of
a wide variety of types were emplaced on the Vietnam border alone.[2] China conducted clearance operations along its border with Vietnam between 1992 and 1999,[3] and between 2005 and 2009.[4]

In 2009, China said it had completed demining along the Yunnan section of its border with Vietnam and that this “represents the completion of mine clearance of mine-affected areas within China’s territory.”[5] However, casualties from landmines continued to be reported in parts of Yunnan bordering Vietnam, where some areas were still marked as mine-affected and press reports said one or two people were injured in this region every year.[6]

Moreover, in 2011, a Foreign Ministry official reported that China maintains a small number of minefields “for national defense.”[7] Two months later, at the Mine Ban Treaty Eleventh Meeting of States Parties, China said that large-scale demining activities had “on the whole eliminated the scourge of landmines in our territories.”[8] At the Maputo Review Conference in 2014, China said it had “basically eradicated landmines on its own territory.”[9] China has not reported on mine contamination along its borders with Russia and India or on operations to clear them.

Program Management

There is no formal mine action program in China. Any mine clearance is conducted by the People’s Liberation Army (PLA) as a military activity.

Land Release

Demining of the Vietnam border was conducted in three “campaigns” in Yunnan province and Guangxi Zhuang Autonomous Region. The first was in 1992–1994 and the second in 1997–1999. Press reports cited claims by the Chinese military that this second clearance operation was the largest in world military history.[10]

However, these two campaigns did not deal with minefields located in disputed areas of the border, where 500,000 mines covered an estimated 40km2. After a technical survey of mined areas, China embarked on a third clearance campaign in Guangxi Zhuang Autonomous Region and Yunnan province in 2005. China stated in 2009 that it had completed clearance of this border after clearing a total of 5.15km2.[11]

In early November 2015, however, China embarked on a further demining operation along the border with Vietnam.[12] According to media accounts, this phase of clearance on the border was set to be completed by the end of 2017, with the clearance of more than 50 minefields covering an area of more than 50km2 in six counties along the border, in areas home to over 50,000 people. It was claimed that more than 470,000 mines remained to be cleared, despite the two other clearance operations in 1992–1994 and 1997–1999.[13]

In August 2016, China reported that it had made “positive progress” in the ongoing phase of the government’s demining operations, saying it was due to finish in 2017.[14] According to a media report in December 2016, demining in the Red River autonomous prefecture in Yunnan province had been completed after eight months of operations, with soldiers having cleared 18 minefields with a size of more than 4.4km2 in the Red River section along the Vietnamese border.[15]

In its CCW Amended Protocol II Article 13 transparency report submitted in March 2017, China reported that in November 2015–February 2017, the Chinese army cleared 18.4km2 of minefields on the Yunnan border.[16] Its latest Article 13 report, submitted in March 2018, recorded no change under Form B “landmine clearance,”[17] though media accounts reported that after an 11-month hiatus, mine clearance had resumed in November 2017 in the Yunnan border area.[18] In May 2018, six hectares 0.06km2 of cleared land were handed over to the local government after the destruction of 8,200 mines and explosive remnants of war. In total 23km2 have been cleared since November 2015 with another 15km2 expected to be cleared by the end of 2018.[19]
