A Xinhua editorial states that the United States will end up harming itself by selling arms to Taiwan. “The Obama Administration of the United States decided on September 21, 2011, to sell arms to Taiwan. Thus, one more time, it ate its own words on an issue involving China’s core interests. … Only when the United States keeps its promises, adequately handles the Taiwan issue, and stops arms sales and military exchanges can it promote healthy and stable progress in the Sino-US relationship. Otherwise, the political credibility of the United States will continue to decline. Eventually it will wipe out its credit and the United States will be its own victim. This is not a threat.”
