Days after giving China a positive vote in congress, Kenny Hulshof was struggling to release a Columbia woman from prison there. Sue Jiang had been held in a Chinese prison and on house arrest since a Tianamen Square demonstration last month. The Chinese ambassador assured Hulshof on Wednesday that Jiang would receive her confiscated passport so she could leave. The recent M.U. grad student was practicing the banned meditative exercise Falun Gong in public. Hulshof says these are the kinds of abuses of civil rights that congress will monitor if China’s Most Favored Nation trade status is approved.
