U.S. President Barack Obama will meet with NATO Secretary-General Jens Stoltenberg at the White House on April 4, the White House announced on March 25.
The two leaders are expected to discuss the fight against the Islamic State group, the migrant crisis, the upcoming NATO summit, and NATO's increased presence in eastern Europe in response to Russia's aggressions in Ukraine.
At the meeting Obama will stress that the United States "stands together with NATO in the wake of the horrific terrorist attacks" in Brussels, where NATO is based, the White House said.
The two will discuss preparations for the NATO Summit on July 8 and 9 in Warsaw, Poland, "including Allied efforts to reinforce deterrence in Europe, address instability on Europe's periphery, and strengthen NATO's base of capabilities and partnerships," it said.
