UK’s Sunak vows to get tough on China if he becomes PM

Rishi Sunak on Sunday promised to get tough on China if he becomes Britain's next prime minister, calling the Asian superpower the "number one threat" to domestic and global security.

The former finance minister's pledge comes after his rival in the final two of the race to lead the ruling Conservative party, Liz Truss, accused him of being weak on China and Russia.
