SEOUL -- North Korea's top diplomat arrived in Moscow on Monday, state media reported, to meet her Russian counterpart, Sergey Lavrov, who visited the North in October. The trip by Foreign Minister Choe Son Hui comes a day after the country claimed to have successfully tested a new solid-fuel hypersonic missile.
The missile launch and Choe's visit highlight Pyongyang's growing focus on two goals: boosting the power and sophistication of its weapons arsenal and deepening ties with Cold War-era partners such as Russia.
