​Beijing: The teenage son of a detained human rights lawyer blocked by Chinese authorities from attending high school in Australia has gone missing in Myanmar while attempting to flee China.

Bao Zhuoxuan, 16, was taken from his hotel on Tuesday by uniformed men in the Burmese town of Mong La, near the Chinese border, according to rights activists helping with his journey.

Bao Zhuoxuan went missing in Myanmar while attempting to flee China.

Mr Bao had been en route to Thailand where he planned to apply for asylum in the United States, having been under constant surveillance and harassment from Chinese authorities since his parents, prominent lawyer Wang Yu and legal activist Bao Longjun, were detained in July amid a sweeping government crackdown on lawyers in China.
