China is such a huge economic power that it's impossible not to do business with them, but our government should do much more not to expose this country to the inroads their companies are making into our economy. Their citizens are very vulnerable to the pressure exerted by this dictatorship. This includes immigrants and the foreign student population who, on the whole, are kept very isolated from other people in the host country. There should be no let-up on the pressure insisting the Chinese government improve their human rights record.
