In an interview with Reuters ahead of his trip to Washington next week for a summit with U.S. President Donald Trump, South Korean President Moon Jae-in said ’strong’ sanctions should be imposed if North Korea tests an intercontinental ballistic missile （ICBM） or conducts a sixth nuclear test.
The comments mark the toughest warning yet by the liberal former human rights lawyer, who was elected in May. "I believe China is making efforts to stop North Korea from making additional provocations, yet there are no tangible results as of yet," Moon told Reuters at the Blue House.
"China is North Korea’s only ally and China is the country that provides the most economic assistance to North Korea," Moon said. "Without the assistance of China, sanctions won’t be effective at all."
“Maybe President Trump believes that there is more room for China to engage North Korea and it seems that he is urging China to do more. I can also sympathize with that message,” Moon said.
