Canada urged to respect rule of law, stop interfering in China's judicial sovereignty

China urged Canada on Thursday to stop interfering in its judicial sovereignty, saying that it's a shared responsibility for all countries to fight drug-related crimes.

Foreign Ministry spokeswoman Mao Ning made the remarks at a regular news conference, after reports quoted Canadian Foreign Minister Melanie Joly as saying that China had executed four Canadian citizens earlier this year due to drug-related charges.

Mao said that China upholds the rule of law and treats all defendants equally regardless of their nationalities.
