Should we boycott China?

Got this email this morning, probably in response to all that's been in this space about Chen Guangcheng:

When are the anti-abortion church groups going to realize the way to stop State-mandated abortions in China is to BOYCOTT China's goods and importers (no more Walmart) to economically get them to change on their one-child policy. As an added plus it would create US jobs.

Here's my reply: 

Thank you for writing. I agree that pro-life Christians should boycott entities that promote or profit from abortion, but more as a moral decision than as a tactic of change. Boycotts may result in change, and that would be all for the good, but I can’t be certain that a boycott of China, for instance, will get them to abandon their one-child policy.

Baptists for Life is founded on the belief that the only means of real change is transformation of individual human hearts through salvation in Jesus Christ. China is a dark, godless country. It’s not just a matter of policy, but of its leaders being under the influence of the Enemy. So, while I believe it’s right not to invest in China, we ought not put our hope in the power of the dollar. We need to pray for change in China, and for the persecuted Chinese Church (Hebrews 13:2).
