WASHINGTON:The United States expects North Korean troops in Russia’s Kursk region to enter the fight against Ukraine in the coming days, US Secretary of State Antony Blinken said on Thursday as he pressed China to use its influence to rein in Pyongyang. Blinken spoke after North Korea conducted its longest-ever intercontinental ballistic missile test earlier on Thursday and South Korea warned that Pyongyang could get missile technology from Russia in exchange for helping with the war in Ukraine. The top US diplomat said there were 10,000 North Korean troops in Russia, including as many as 8,000 in the Kursk region where Ukrainian forces continue to hold territory after fighting their way into the Russian border area in August. At a press conference with Defense Secretary Lloyd Austin and their South Korean counterparts, Blinken said Russia has been training the North Korean soldiers in artillery, unmanned aerial vehicles, or drones, and basic infantry operations, indicating they “fully intend” to use the forces in frontline operations. They would become legitimate military targets if they enter the battlefield, Blinken said. “We’ve not yet seen these troops deploy into combat against Ukrainian forces, but we would expect that to happen in the coming days,” he said. During their meeting, the US and South Korea discussed a range of options for responding, Blinken added, saying Moscow’s use of North Korean soldiers in its “meat grinder” war against Ukraine was a “clear sign of weakness.” Austin said the US would announce new security assistance for Ukraine in coming days. Blinken and his South Korea and Japanese counterparts condemned the ICBM launch as a flagrant violation of UN Security Council resolutions. The flight-time of the missile was 87 minutes, according to South Korea, putting nearly all of the United States within range. The Kremlin on Thursday declined to comment when asked if Russia was helping North Korea to develop its missile and other military technology. Blinken said Beijing, like Washington, should be very concerned about what Russia might be doing in order to enhance North Korea’s military capacities because it was destabilizing to Asia.
