North Korea's Kim Jong-un arrives in Russia for Putin visit

The big picture: The Kremlin wrote in a Telegram post that Kim's visit will take place "at the invitation of" Russian President Vladimir Putin, but did not specify exactly when or where it would take place.

• U.S. National Security Council spokesperson Adrienne Watson warned last week that "arms negotiations" between Moscow and Pyongyang "are actively advancing."
• Watson added that potential arms sales were discussed during a recent visit to North Korea by Russian Defense Minister Sergei Shoigu.

Worth noting: The trip marks Kim's first known visit abroad in more than four years, Reuters reported.

• The trip will include a one-on-one meeting between Kim and Putin, as well as a dinner in Kim's honor, Kremlin spokesperson Dmitry Peskov told reporters Tuesday, per Russia's Interfax news agency.
• No press conferences are planned, Peskov added.

State of play: White House national security adviser Jake Sullivan warned last week that North Korea would "pay a price" if it decided to supply weapons to Russia.

• A U.S. official confirmed last year, citing downgraded U.S. intelligence, that Russia's Ministry of Defense was buying millions of rockets and artillery shells from North Korea.
• As the war in Ukraine has stretched on, Russia has turned to other adversaries of the U.S., including China and Iran, to aid its war effort.
