Canadian undergoing "administrative punishment" for working illegally: China

China's foreign ministry said on Thursday that a Canadian national is undergoing "administrative punishment" for working illegally after Canada's government said a third Canadian citizen had been detained in China.

There is clear consular communication between Canada and China, ministry spokeswoman Hua Chunying told a daily news briefing.

China last week detained two other Canadian citizens, saying they were both suspected of endangering China's national security.
