China Bars Professor From Attending Conference in U.S.

China has barred a literature professor at the Beijing Film Academy from traveling to the United States to attend meetings of the Association for Asian Studies, the Associated Press reported. Cui Weiping had a U.S. visa, but was blocked from leaving with no official reason given. She believes that she is being punished for Twitter posts expressing outrage at the jailing of a political activist, and her speaking out about the anniversary of the Tiananmen democracy protests.
