Since the no-deal summit, Pyongyang has been seen beefing up diplomacy with its traditional major-power backers, China and Russia, while calling for flexibility in Washington’s hard-line stance in hitherto unfruitful nuclear negotiations. Kim’s entourage included two vice chairmen of the North’s ruling Workers’ Party’s Central Committee — Kim Phyong-Hae and O Su-yong — and top diplomats, Ri Yong-ho and Choe Son-hui, according to the North’s Korean Central News Agency. The state media did not mention whether first lady Ri Sol-ju was on board. Kim Yong-chol, one of the North’s key nuclear negotiators involved in talks with the United States, was not mentioned either. It is the first time that he has not accompanied the leader on an overseas trip.

The Kremlin has confirmed that the summit will occur in Vladivostok on Thursday. Yuri Ushakov, a Kremlin aide, has told reporters that the main summit agenda item will be how to resolve the North Korean nuclear standoff. It also stressed that Russia would be the first country that Kim visits after his recent re-election as the chairman of the State Affairs Commission, the country’s highest administrative apparatus. Due to his hectic domestic schedule, Putin is expected to arrive in Vladivostok on Thursday. But Yury Trutnev, Russia’s deputy prime minister and presidential plenipotentiary envoy to the Far Eastern Federal District, could welcome Kim at a Vladivostok station.

The Putin-Kim summit is likely to take place at Far Eastern Federal University as Kim’s security and protocol staffers have been spotted making final summit preparations, with the national flags of Russia and the North hung on campus light poles. The summit agenda is expected to center on peace efforts on the divided peninsula, economic cooperation and bilateral ties. It may also include the fate of around 10,000 North Korean workers in Russia who will face repatriation by the end of this year under U.N. sanctions banning any country for issuing new visas for such workers, a crucial source of foreign currency for the cash-strapped regime.

Thursday’s summit will be the first one between the leaders of the two countries in eight years, after Kim’s father and the North’s former leader, Kim Jong-il, met then Russian President Dmitry Medvedev in 2011. Kim’s latest summit diplomacy is part of the diplomatic outreach that he launched last year to ease global isolation and advance his economic agenda following his claim in late 2017 to have completed the state nuclear force.

In Washington, the State Department stressed the importance of North Korea’s denuclearization. “The United States and the international community is committed to the same goal — the final, fully verified denuclearization of North Korea. It is Chairman Kim’s commitment to denuclearization upon which the world is focused,” a department spokesperson said when asked to comment on the Kim-Putin summit. U.S. Special Representative for North Korea Stephen Biegun and his Russian counterpart, Deputy Foreign Minister Igor Morgulov, will continue consultations to “bridge any gaps on the way forward,” the spokesperson added. Following the summit, Kim is expected to take a tour of Vladivostok or its vicinity, and return home Friday.
