President Obama holds a joint press conference on nuclear security

President Barack Obama was in The Netherlands and Belgium on Tuesday for meetings with global leaders and for the Nuclear Security Summit.

President Barack Obama said the United States is concerned about further encroachment by Russia into Ukraine during a joint news conference with Dutch Prime Minister Mark Rutte amid a flurry of diplomatic activity in the Netherlands.

Obama says that would be a bad choice for Russian President Vladimir Putin to make. He says there’s another path available to Russia, and that world leaders have created the framework for additional costs to be imposed on Russia if it takes the next step by moving further into Ukraine.

Obama says he believes if Ukrainians have a choice, they’d seek to have a relationship with both Europe and Russia. He says it’s not a zero-sum game, and that the U.S. is not recognizing Russia’s annexation of Crimea.
