They don't need to though, as they are inherently racist by nature.

Yeap, even to those few permanent foreign residents of China.

I knew of a british guy who did not fit the typical blonde haired, blue eyed european look. But he had a permanent green card for china, chinese wife, two daughters in china, and a business in China.....yet at guangzhou airport, they'd pull him into the foreigners line, he'd tell the airport official or whoever to f*** off, and show his permanent residency card, and explain in chinese....yet still they would tell him he was in the wrong line and he had to move.

China, insular and racist, nothing will change. Nothing.
