I have the same situation with a good french friend of mine. He is married with a chinese woman. They currently build an house in the south of France, and it's problematic for the money from China (the chinese parents of this girl, who give some money to them for the construction).. If I am︀ right it's like they are capped at USD 50K a year, they can send outside︁ China lol. Crazy.
And at a second level, it's to justify to the French bank︂ (and notary), the origin of fund in China..
