On February 21, 2021, police in Chongqing announced that they were engaged in “online pursuit” of a 19-year-old living outside of China after he "slandered and denigrated the heroic officers and soldiers protecting our borders" on Weibo, based on a 2018 law criminalizing the "insult or slander" of heroes and martyrs." The young man, Wang Jingyu, had commented on the revelation that four Chinese troops had been killed in a bloody brawl in the Galwan Valley, along the disputed China-India border, that left 20 Indian soldiers dead in June 2020.
"I think online pursuit refers only to inside China," Wang told Radio Free Asia. "As for criminal detention, right now I'm really free, and I want for nothing. I don't know what this notice means."
