Team China's foreign-born Olympians

• Eileen Gu has garnered most of the headlines, but she's just one of 30 foreign-born athletes on Team China. About half are North American men's hockey players, and all maintained citizenship, per USA Today.
• Gu won't say whether she renounced her U.S. citizenship, and the Olympics website — which previously said she did — was changed on Feb. 10, adding to the mystery, Voice of America reports.
• "I told China that I'll never give up my [U.S.] passport, and they said that's fine," said goalie Jeremy Smith, a Michigan native who's eligible to represent China due to a stint with Chinese club Kunlun Red Star.
• Of note: Other countries have used naturalized foreign athletes for decades, but few if any of those have laws as strict as China’s.

Between the lines: China may have relaxed its citizenship rules, but it's still requiring a certain allegiance: Hockey players used Chinese names, and at least one player wasn't allowed to speak English in an interview.

What to watch: Susan Brownell, an American anthropologist and expert on Chinese sports, views this "politically sensitive matter" as a sort of tight-lipped experiment.

"After the Beijing Games, they're going to assess public opinion about having those athletes in the team. Was it good for Chinese sports, patriotism and the government's image, or was there a negative nationalist backlash?"

The bottom line: China, hosting its first-ever Winter Olympics amid geopolitical turmoil, wants to put its best foot forward in Beijing. And it's willing to bend long-standing nationality laws to do so.
