NATO chief Mark Rutte said Thursday he aimed to work jointly with returning US leader Donald Trump in confronting the "dangerous new developments" linked to North Korea's entry into the Russian war on Ukraine.

"I look forward to sit down with Donald Trump to discuss how we can face these threats collectively," Rutte told reporters at a European leaders' meeting in Budapest, warning that Moscow's delivery of weapons technology to Pyongyang posed "a threat not only to the European part of NATO but also to the US mainland."
