Is there anything I can do for my friend?

His girlfriend (who happens to be my BFF) just broke up with him, recently, and he's so depressed. She broke up with him because she's Chinese, and her parents wanted her to break up with him. What's more, they want her to go back with them to China, and marry her off to her first cousin, once removed! Now, he's depressed over the breakup, her leaving, and her marriage to her cousin! She can't break away from that, because she was promised to her cousin, even at an early age! And besides, since they are Chinese, they're very family-oriented, want to please the parents (but she's depressed over the breakup too), and they want to keep the bloodline pure, so they don't want her marrying someone who is non-Chinese (i.e., my friend)!
