766, I believe your instincts are correct but your energies are misplaced. You are entirely correct that China is not, as the former president claimed, "a strategic partner." They are as they have shown themselves to be in the present crisis: a country incapable of or unwilling to abide by the rule of international law, and, more importantly, a rival to American interests in East Asia. Consequently, they should be contained militarily. This means increasing sales of arms, including the Aegis Battlefield Management System, to Taiwan, strengthening our ties to Japan and South Korea, and increasing our support for the Dahli Lama.
At the same time, we need not isolate China economically. Rather, we should engage them. By encouraging trade with the PRC, we increase capitalism therein. As the night follows the day, so democracy follows capitalism. The government cannot grant economic freedom and then withhold political freedom. It just does not work. If you want examples, look to the American and French Revolutions and, more recently, the end to one-party rule in Mexico, South Korea, and Taiwan. As trade increases, a middle class grows which challenges one part rule and ultimately forces democracy. This is especially true in a country that claims to be "communist" yet practices capitalism. With the economic ideology of Mao and Marx long since discarded, what, the middle class will ask, is the continuing justification for the political power of the communist party.
When you buy something that says "Made in China," 766 you do perhaps increase the comfort of Jiang Zemin and his ilk. But at the same time you sow the seeds of the destruction of the Communist Party of the Peoples' Republic of China by sending money to a growing middle class that is on the internet, believes in democracy, and practices Falun Gong. Patience, Grasshoppah, have faith in capitalism.
