Ukrainian Envoy: U.S. Affirms Opposition To Russian Takeover Of Crimea
Ukraine's ambassador to the United Nations said the Trump administration fully supports his country's territorial integrity and independence and will never accept Russia's annexation of Crimea.
At a news conference in New York on February 1, Volodymyr Yelchenko said U.S. ambassador to the UN Nikki Haley told him the United States is "completely against the way Russia is dealing with the eastern part of Ukraine."
"She confirmed the U.S. position on Crimea, that the annexation will never be accepted," he said, adding that he was "absolutely satisfied" with her answers to inquiries about Russia's annexation of Crimea in 2014.
While he was campaigning for office last year, President Donald Trump told ABC News he would "take a look" at the Crimea question and "that the people of Crimea, from what I've heard, would rather be with Russia than where they were, and you have to look at that, also."
While the Trump administration may be considering establishing a closer relationship with Russia, Yelchenko said, that is "not happening at the price of Ukraine."
The U.S. Mission to the UN said Haley reaffirmed support for Ukraine's territorial integrity in her meeting with Yelchenko.

Poroshenko Says He Plans To Hold Referendum On Ukraine Joining NATO
Ukrainian President Petro Poroshenko told German media that he is planning a referendum on whether Ukraine should join NATO now that polls show 54 percent of Ukrainians favor such a move.
"Four years ago, only 16 percent favored Ukraine's entry into NATO. Now, it's 54 percent," Poroshenko told Germany's Funke Mediengruppe newspaper chain in an interview published on February 2.
"As president, I am guided by the views of my people, and I will hold a referendum on the issue of NATO membership."
He vowed to "do all I can to achieve membership in the transatlantic alliance" if people vote for that. He said Ukraine's military will be up to NATO standards by 2020.
NATO and Ukraine have had a close relationship since the early 1990s, and the alliance's website says their ties are one of the "most substantial" of NATO's partnerships.
However, any move by NATO to admit Ukraine would spark tensions with Russia.
Poroshenko also told the newspaper that Ukraine is making progress on joining the European Union by reducing its budget deficit and curbing corruption.
"Europe should realize that it would be more secure, reliable, and happier with Ukraine," he said.

Putin Heads To Budapest Amid Concerns Over EU Unity
Russian President Vladimir Putin is heading to Hungary for his second visit in two years, a development that has many in the European Union looking on with concern.
Hungarian Prime Minister Viktor Orban’s February 2 meeting with Putin comes at a time of heightened worries within the bloc about the views of new U.S. President Donald Trump, who has expressed disdain for the European Union and a desire for closer relations with Moscow.
"We are concerned [about the trip], there is no doubt about it," an EU official requesting anonymity told RFE/RL on February 1. "It is Putin’s year. He's looking at a divided Europe, which the Visegrad Four (the Czech Republic, Hungary, Poland, and Slovakia), especially Hungary, are making more divided due to actions like [inviting Putin to Budapest], and a United States that for the first time is providing no counterbalance to [Putin].”
Putin's visit -- his second to Budapest in two years and his third official meeting with Orban in that time -- is primarily to discuss economic issues, including the controversial Paks nuclear-power plant that Russia is contracted to build and further agreements on natural-gas purchases.
Putin has received few invitations to EU countries since Moscow’s illegal 2014 takeover of Ukraine's Crimea region and the introduction of EU sanctions against Moscow over its interference in Ukraine.
