I think it is probable that China start to colonize Mars before US has the ability to. Next, they start to claim area after area, while also dominating the earth economy. It will not stabilize the geo-political landscape - it will complicate it.
If China establishes colonies, good for them. When England colonized America, it began the downfall of Spains empire (more or less), but no one is crying that Spain didn't become the global power it 'should' have become.
Did it ever occur to you that:
1. No Chinese would ever think such self-hating thoughts.
and
2. Such thoughts did not originate from your own reasoning, but were learned through various channels?
It's not like it matters, as Martian colonization is less likely than human extermination via a robot takeover, but still...
2. How is wishing that all of humanity makes progress rather than just your own country self-hateful? Isn't that the ideal?
3. I know a lot of Chinese people who went to the U.S. for undergrad and really care about both countries, which is a counterexample to your #1.
