U.S. Secretary of State Antony Blinken is in Latvia Tuesday for talks with the country's leaders and a NATO ministerial meeting as the alliance expresses concern about Russia's military buildup along the border with Ukraine.
Blinken's schedule in Riga includes sessions with Latvian President Egils Levits, Prime Minister Krisjanis Karins and Foreign Minister Edgars Rinkevics. He is also due to meet with NATO Secretary General Jens Stoltenberg ahead of the ministerial talks later in the day.
Levits told reporters after his own talks with Stoltenberg on Monday that Russia's military presence represents direct pressure on Ukraine, and that NATO "will remain in solidarity with Ukraine."
Stoltenberg called on Russia to reduce tensions in the region, saying the military buildup is "unprovoked and unexplained."
"Any future Russian aggression against Ukraine would come at a high price and have serious political and economic consequences for Russia," Stoltenberg said.
A main focus of work at the NATO ministerial meeting is updating what the group calls its Strategic Concept, which was last changed a decade ago.
Stoltenberg said it is important to revisit the strategic document given the changed nature of the threats NATO faces, what he called a "more dangerous world."
"We see the behavior of Russia, we see cyber, we see terrorist threats, we see proliferation of nuclear weapons," Stoltenberg said. "And we see the security consequences of China which is now becoming more and more a global power."
The talks in Riga also come as NATO members Latvia, Lithuania and Poland deal with a border crisis with neighboring Belarus.
The European Union accuses Belarusian President Alexander Lukashenko of enticing thousands of migrants, mainly from the Middle East, to travel to Belarus and try to cross into Latvia, Lithuania and Poland in order to destabilize the European Union. The EU says Lukashenko is retaliating for sanctions it imposed against his government.
Blinken is scheduled to travel Wednesday to Sweden to meet with fellow ministers from the Organization for Security and Cooperation in Europe, and to discuss bilateral ties with Swedish officials.
