Theresa May will be looking for guarantees from Donald Trump that American won't "stand idly by" in the face of Russian aggression.
ITV News Political Editor Robert Peston believes the Prime Minister hopes the US President will his signal support for NATO - rather than an intention to loosen sanctions against Russia.
Mr Trump has previously described NATO as "obsolete," and suggested he might be willing to drop sanctions imposed by Barack Obama.
Peston, who is in Washington, said of the upcoming meeting between Mrs May and Mr Trump: "She wants him to basically say he stands by the principle of NATO: That an attack on one member is an attack on all.
"This is particularly important when we see the confidence of Vladimir Putin, and his very clear aims of exerting greater influence over the countries of the former Soviet Union."
He added that there were "tremendous fears" in Baltic States about a future Russian invasion.
Russia's UK embassy criticised a speech by Theresa May about Vladimir Putin - through rhyming poetry.
The embassy chided the Prime Minister after she called on US President Donald Trump to "beware of" the Russian leader.
In a speech delivered on Thursday, Mrs May urged Mr Trump to engage with the Kremlin "from a position of strength."
Her comments appeared to have irked the London-based Russian embassy, who tweeted their response in the form of ABAB poetry.

The Prime Minster called on the US to renew its "special relationship" with the UK, evoking the memory of Margaret Thatcher and Ronald Reagan as she addressed congressmen from the Republican Party.
Mrs May received several standing ovations during her speech in Philadelphia, a day before her historic meeting with President Donald Trump at the White House on Friday.
She said the two countries had a "responsibility" to offer leadership to the world, condemned the "malign influence" of Iran, vowed to fight the so-called Islamic State and promised to "stand up" to the security of Israel.
