Many people think that the United States’ influence has waned and its image has been tarnished. I have yet to arrive at the same conclusion. Since I was released from a Chinese prison in April 2007, having served five years for investigating labor unrest, I have spoken to a great number of people around the world about this very topic. In my mind, the United States remains a great country, and its people a great people. It continues to be the only global force with the authority to promote democratization and safeguard freedom and security.

I do believe, however, that the United States has a consistency problem. It is a country that was founded on the principles of freedom, democracy, and certain inalienable rights of the common people, but the desire to meet short-term interests tends to compromise faithfulness to these principles. That inconsistency weakens American credibility.

Since the violent crackdown on protesters in Tiananmen Square in 1989, U.S. policy toward China has been fickle, even erratic.

Many people wrongly assume that pressuring the Chinese government on human rights triggers ill will toward Americans on the part of ordinary Chinese citizens. In fact, it is the United States’ constant seesawing that reinforces the popular belief that Americans only act for their own material gain. The lofty statements followed by inaction have led the Chinese people to conclude that some American politicians, scholars, and businesspeople are hypocrites. Their self-imposed censorship when dealing with the Chinese government is disappointing. I have never opposed trading with China, but I cannot support a policy that is so...
