On April 15, 1989, Hu Yaobang died. Hu had been general secretary of the Communist Party from 1982 to 1987, and recognized for his leanings toward economic reform in China. His death led to demonstrations around China, some of them in Tiananmen Square. On June 4, 1989, Tiananmen became the focus of the government's wrath, and in the intersections of the broad streets around the plaza, the government cracked down brutally. Since then, it has been a government tradition to start cracking down on protesters, critics, and dissidents before April 15, and this year is no different. China watchers say the strictures have already begun with warnings to some and detentions for others. I checked with foreign journalists over the weekend, and they say they're aware of the crackdowns, but are not feeling any heat themselves. Yet.
