Han is a cultural concept, as is American. The government is not desperate, because Han culture is real: speaking Chinese, reading Chinese characters, looking like Chinese, then you would be accept as Chinese. Appearance is a issue for Westerners, but not a issue for all other indigenous ethical groups.

Remember, being Han is not something people are ashamed of, in ancient East Asia, it is an honor, the hallmark of civilization, as was Rome, as is being American. Realistically, earn an ticket to the enormous economic opportunities China is offering is not a bad deal either, if you already look like one.
