U.S. Secretary of State John Kerry is having a busy day. He spoke with the Russian foreign minister, met with and appeared in a joint press conference with his Ukrainian counterpart, and warned of new sanctions on Russia. And all before lunch.

Here's a play-by-play of Kerry's day:

In a phone call with Russian Foreign Minister Sergei Lavrov, Kerry discussed the landmark Cold War-era arms treaty that the U.S. just accused Russia of violating when it tested a ground-launched cruise missile.

The two men also reportedly decided that the fighting between Ukrainian troops and pro-Russian separatists near the site of the MH17 crash needed to stop. Man, oh man, check out this humdinger of a joint statement. From Reuters:

"Lavrov and Kerry 'have agreed with the necessity for the scrupulous fulfillment of the U.N. Security Council resolution ... demanding the international and independent character of the ... investigation and to stop fighting in the area where its debris is located.'"

If that sounds a little stilted that's because Kerry said this following his meeting with Ukrainian Foreign Minister Pavlo Klimkin.  

Kerry also said the United States is preparing new sanctions against Russia. From the AP:

Secretary of State John Kerry issued a new warning Tuesday that the U.S. and European Union are prepared to slap additional sanctions on Russia if it continues to ship weapons, funds and fighters across its border to support the separatists in eastern Ukraine.
