WASHINGTON — With Russia-tinged investigations swirling around his administration, President Trump has yet to fulfill a campaign pledge of closer cooperation with Moscow. A planned trip by Secretary of State Rex Tillerson to Russia could test if detente proves anything more than talk.
In a move alarming US allies, Tillerson plans to skip a meeting of NATO foreign ministers in Belgium next month, according to US officials. The top American diplomat almost always attends such gatherings, and Tillerson will follow up his absence in Brussels by traveling to Russia’s capital shortly afterward.
The juxtaposition of the trips — one taken and one avoided — has reinforced concerns about America’s commitment to NATO, which Trump has repeatedly fueled by dressing down allies as deadbeats who aren’t paying enough for their own defense and who take US help for granted.
So far, though, Trump has yet to make major steps as president to bring Russia and the United States closer together.
As a candidate, Trump opened the door to potentially rolling back the sanctions imposed on Russia after its annexation of Ukraine’s Crimea region in 2014, a move many Democrats and Republicans in Congress oppose.
But as president, Trump has tamped down such suggestions as long as Russia fails to live up to its various commitments to end the fighting in Ukraine.
His administration also has resisted Russia’s calls to join forces against the Islamic State in Syria, where the former Cold War foes have long backed opposing sides in a civil war.
The Pentagon is continuing only what it calls US-Russian ‘‘deconfliction’’ contacts, designed to ensure their forces don’t accidentally collide on Syria’s crowded battlefield and contested skies.
But Trump’s biggest roadblock to a new Russia approach may be the political realities at home.
In a remarkable public disclosure Monday, FBI Director James Comey said the bureau is investigating whether Trump campaign associates coordinated with Russian officials as Moscow sought to sway the US presidential election.
Several congressional committees are also investigating, ensuring the allegations of Russian meddling — and questions about Trump campaign collusion — stay in the spotlight for months to come.
Trump has denied any collaboration between his campaign and Russia. As a candidate, he spoke frequently of his admiration for Russian President Vladimir Putin and said improving relations with the traditional US adversary would be positive. He argued that Russia shared America’s goal of defeating Islamic State extremists.
That’s about as far as the new relationship has gone.
‘‘Tillerson will need to publicly outline what he hopes to accomplish when he visits Moscow and what is the basis for US policy toward Russia,’’ said Heather Conley at the Center for Strategic and International Studies.
The prospect of Washington and Moscow teaming up, given Russia’s recent actions in Ukraine, has sent chills through much of Europe. Candidate Trump exacerbated concerns by calling NATO ‘‘obsolete’’ and suggested the United States might not defend allies if they aren’t paying enough for collective defense. As president, Trump has insisted the United States is committed to NATO.
The State Department wouldn’t provide details Tuesday about the purpose of Tillerson’s trip to Russia or whom he would meet there.
