Battle of Laoshan (1984)
라오산 전투 (1984)
Fighting beginning with China’s seizure of the Laoshan heights on the Yunnan border in April 1984 and Vietnamese counterattacks. Often discussed alongside the Zheyinshan operation as the Two Mountains fighting, it was a major episode in the unresolved post-1979 border conflict and led to prolonged positional fighting and unit rotations.
In depth
Contest for border heights
China’s 1979 withdrawal produced neither a peace treaty nor an agreed border. Shelling and limited attacks continued. In spring 1984 Chinese forces attacked at Laoshan and Zheyinshan under Kunming Military Region commander Zhang Zhixiu.
Counterattacks and prolonged fighting
Vietnamese counterattacks led to sustained infantry and artillery fighting over heights and supply routes. The initial seizure must be distinguished from subsequent years of positional warfare. Competing boundary claims and place names also make each side’s language of liberation or invasion a political claim.
Significance
Chinese units rotated through the front, accumulating combat experience; Vietnam bore the burdens of both Cambodia and northern border defence. The episode shows that war between the two socialist states did not end with the brief 1979 invasion.
