Xi and Kim vow closer ties, citing "hostile" foreign forces

What they're saying: The two countries' governments "are now staunchly advancing toward a bright future by smashing the high-handedness and desperate maneuvers of the hostile forces on the strength of militant friendship and blood ties even under the complicated international situation," Kim said in a statement.

• "Despite the increasingly rampant anti-socialist attempts by the imperialists and the rapidly changing relations between or among countries in the wake of the Cold War, the deep-rooted" relations between China and North Korea were "strengthening," he added.

The big picture: The Biden administration last month extended for another year an executive order that's been in place for more than a decade, which declares a national emergency over the nuclear threat from North Korea.

• The administration and U.S. lawmakers have also taken steps against China's government — including sanctions against Chinese officials for rights abuses and banning Americans from investing in companies linked to the Chinese military and its surveillance activities.
