US keep seeing themselves as the superpower - a superpower that is paying a rival (and developing) country instead of fighting against it. Why can't we move past that and think of win-win scenarios for both countries.
Taking this logic, the media in China should state: China is buying US debt - Yes, US. China is a significant holder in US debt and bought a lot when the economy turned sour in 2008. (Terrible investment since the US would just turn around and force the RMB to appreciate against the dollar). This in turn supported the US economy and the world's economy.
As I read the article, I see this as a win-win scenario. US gets bandwidth and China gets money. Cross border cooperation should be encouraged - not discouraged.
