SEOUL (Reuters) - South Korean President Moon Jae-in said on Thursday China should do more to rein in North Korea's nuclear programme and he would call on President Xi Jinping to lift measures against South Korean companies taken in retaliation against Seoul's decision to host a U.S. anti-missile defence system.

In an interview with Reuters ahead of his trip to Washington next week for a summit with U.S. President Donald Trump, Moon said 'strong' sanctions should be imposed if North Korea tests an intercontinental ballistic missile (ICBM) or conducts a sixth nuclear test.
