U.S. President Barack Obama has met with Kazakh President Nursultan Nazarbaev at the U.S. Embassy in The Hague.
U.S. officials did not say what was discussed.
Kazakhstan is a close ally of Russia and a key member of the Moscow-led Customs Union.
But Nazarbaev has appeared lukewarm in his comments about Russia's seizure of Ukraine's Crimean Peninsula.
Northern regions of Kazakhstan that border Russia have large Russian-speaking communities.
Obama and Nazarbaev spoke via phone on March 11 about the Ukraine crisis, one day before Nazarbaev canceled a visit to Moscow.
Obama and Nazarbaev are in the Netherlands for a nuclear security summit.
The two presidents issued a joint statement on March 25 on their countries' "shared commitment to nonproliferation and strengthening nuclear security."
