North Korean Foreign Minister Ri Yong-ho in Beijing on Thursday on a three-day trip to secure China’s support for the removal of economic sanctions on the regime.

Ri arrived at Beijing Capital International Airport on Thursday afternoon for a three-day stay on the way back from trips to Vietnam and Syria. He is scheduled to hold talks with Chinese Foreign Minister Wang Yi and other senior officials, with the aim of receiving greater support for North Korea’s calls to lift economic sanctions.

He is also expected to be briefed on last week between Chinese Communist Party leader Xi Jinping and U.S. President Donald Trump at the G20 summit, where Trump that his second meeting with Kim is likely to take place early next year.

China remains North Korea’s most important economic and political ally but has previously agreed to United Nations economic sanctions aimed at pressuring the regime to abandon its nuclear weapons program. However, countless reports have detailed cases of Chinese officials and companies violating these sanctions, be it from the of luxury goods to helping them their tourist industry that provides a key source of foreign capital.

In September, both China and Russia that the sanctions on North Korea be lifted. China’s foreign affairs minister Wang Ji called for the need to be “modified.”

“A provision in the Security Council resolutions that the council is prepared to modify the sanction measures in light of the DPRK’s [North Korea’s] compliance,” he said at the time.

“Now given the positive developments in the inter-Korean and DPRK- US relations, and the DPRK’s important pledges and actions on denuclearization, China believes that the Security Council needs to consider invoking in due course this provision to encourage the DPRK and other relevant parties to move denuclearization further ahead,” he continued.

Russian Foreign Minister Sergei Lavrov has criticized Western nations for “stubbornly” refusing to agree to remove sanctions.

“Any negotiation is a two-way street,” he said. “Steps by the DPRK (North Korea) toward gradual disarmament should be followed by the easing of sanctions.”

Ri’s trip comes off the back of his trip to Syria to dictator Bashar Al-Assad, where he argued that the two countries face the same “enemy” and called on increased cooperation between them.
