President-elect Donald Trump will face the challenge of a growing relationship between Russia and North Korea as the two countries strengthen security ties and nuclear capabilities. NBC News' Janis Mackey Frayer reports that Trump may need to cooperate with China as the region's superpower before Russia's fight against Ukraine expands to include more of Asia.

BRUSSELS -- NATO and the European Union are ramping up efforts to persuade China to help get North Korea to stop sending troops and other support to Russia to back its war on Ukraine.

That "could serve Chinese interests if it helps prevent a Russian defeat and brings an end to the war that favors Moscow, but the presence of North Korean troops in Europe could fuel deeper European involvement in East Asian security, which Beijing opposes," Glaser told Newsweek.
