BEIJING - China accused the United States of "prejudice" on Saturday after the US State Department renewed a call for Beijing to fully account for its bloody crackdown on pro-democracy demonstrators in June 1989.The United States should "immediately rectify its wrongdoings and stop interfering in China's internal affairs so as not to sabotage China-US relations," Foreign Ministry spokesman Hong Lei said in an English-language statement released via the official Xinhua news agency.China has already reached a "clear conclusion" about the events of 1989, Hong said.The US State Department, in a statement released on its website, said China should "end harassment of those who participated in the protests and fully account for those killed, detained, or missing."After initially tolerating the student-led demonstrations in the spring of 1989 centered on Beijing's Tiananmen Square, the Communist Party sent troops to crush the protests on the night of June 3-4, killing hundreds, according to rights groups.
