Canada updates travel advisories for US, urges 'high degree of caution' in China

Canada updates travel advisories for the US and China amid increased tensions. Canadians staying in the US for over 30 days must now register, or face penalties, the advisory in line with the US's new requirement said. Canada updated its travel advisory to China as well after foreign affairs minister Melanie Joy said earlier this week that China executed four Canadians in recent months.
