MOSCOW (Reuters) -- Russian President Vladimir Putin is unlikely to bow to a sanctions ultimatum expiring this Friday from US President Donald Trump, and retains the goal of capturing four regions of Ukraine in their entirety, sources close to the Kremlin told Reuters.
Trump has threatened to hit Russia with new sanctions and impose 100 percent tariffs on countries that buy its oil -- of which the biggest are China and India -- unless Putin agrees to a ceasefire in Russia's war in Ukraine.
Putin's determination to keep going is prompted by his belief that Russia is winning and by skepticism that yet more US sanctions will have much of an impact after successive waves of economic penalties during 3-1/2 years of war, according to three sources familiar with discussions in the Kremlin.
The Russian leader does not want to anger Trump, and he realises that he may be spurning a chance to improve relations with Washington and the West, but his war goals take precedence, two of the sources said.
Putin's goal is to fully capture the Ukrainian regions of Donetsk, Luhansk, Zaporizhzhia and Kherson, which Russia has claimed as its own, and then to talk about a peace agreement, one of the sources said.
"If Putin were able to fully occupy those four regions which he has claimed for Russia he could claim that his war in Ukraine had reached his objectives," said James Rodgers, author of the forthcoming book "The Return of Russia."
The current talks process, in which Russian and Ukrainian negotiators have met three times since May, was an attempt by Moscow to convince Trump that Putin was not rejecting peace, the first source said, adding that the talks were devoid of real substance apart from discussions on humanitarian exchanges.
Russia says it is serious about agreeing a long-term peace in the negotiations but that the process is complicated because the two sides' stances are so far apart. Putin last week described the talks as positive.
Moscow’s stated demands include a full Ukrainian withdrawal from the four regions and acceptance by Kyiv of neutral status and limits on the size of its military –- demands rejected by Ukraine.
In a sign that there may yet be an opportunity to strike a deal before the deadline, Trump's special envoy Steve Witkoff is expected to visit Russia this week, following an escalation in rhetoric between Trump and Moscow over risks of nuclear war. On Monday, Russia said it was no longer bound by a moratorium on short- and medium-range nuclear missiles.
The Kremlin did not respond to a request for comment for this story. All the sources spoke to Reuters on condition of anonymity because of the sensitivity of the situation.
