KEIV — High-stakes diplomacy continued on Friday in a bid to avert a war in Eastern Europe. US President Joe Biden announced that American troops "will be moved" to Eastern European NATO countries “in the near term” as Russia said that it would not start a war in Ukraine.

However, Moscow warned that the US and NATO have ignored its demands and left little room for compromise in the crisis.

President Vladimir Putin told his French counterpart Emmanuel Macron that the West has ignored Russia's key concerns over NATO expansion and the deployment of alliance weapons and forces.

Meanwhile, Ukraine's president has called on the West not to "panic" over the Russian threat.

The urgent international efforts come as 100,000 Russian troops are massed near Ukraine's border and the Biden administration worries that the Kremlin will mount some sort of invasion within weeks.

Ukrainian President Volodymyr Zelenskyy has called on the West to remain calm over the tensions with Russia, in spite of the suspicions that it plans to invade his country.

"There are no tanks in the streets. But media give the impression, if one is not here, that we have a war, that we have army in the streets... That's not the case,” the Ukrainian leader said during a news conference for foreign media on Friday afternoon.

"We don't need this panic,” Zelenskyy exclaimed, “We need to stabilize the economy.”

He was speaking as diplomatic efforts continued to defuse the crisis brought by the build-up of Russian forces on Ukraine's borders.

The temperature has been cranked up a notch since Wednesday when Washington and NATO both rejected Moscow's demands for security guarantees in Europe.

"The probability of the attack exists, it has not disappeared and it was not less serious in 2021," but "we do not see a higher escalation than the one which existed last year," Zelenskyy said.

The president chided international media and "even respected heads of state", who would have people believe that there was already a war all over the country, "that there are troops advancing on the roads. But that's not the case," he added.

"The responses of the United States and NATO have not taken account of Russia's fundamental concerns," the Kremlin said following an hour-long phone call on Friday between Putin and his French counterpart Macron.

"The key question has been ignored, namely how the US and their allies count on... putting into practice the principle according to which no one should reinforce its security to the detriment of other countries," the Russian president said, according to the Kremlin statement.

It added that Russia will "decide on its reaction" after studying the detail of the replies from its geopolitical rivals.

The Elysée Palace put a positive gloss on the call, saying that Macron and Putin agreed on the "necessity for a de-escalation" and for "dialogue" to continue over the Ukraine crisis.

"President Putin expressed no offensive intention... he said very clearly that he was not looking for confrontation," Macron's office said.

President Zelenskyy called on the West to remain calm over the tensions with Russia, in spite of the suspicions that it plans to invade his country.

Despite the messages coming out of Moscow playing down the prospect of war, the Belarusian leader said his country would fight alongside Russia in the event of conflict.

Alexander Lukashenko said he would welcome "hundreds of thousands" of Russian soldiers into his country if either Belarus or Russia were attacked, to "defend this land".

The Pentagon said on Friday that the Russian leader had total flexibility when it came to military options.

Defense Secretary Lloyd Austin said Putin could use any portion of his force of an estimated 100,000 troops to seize Ukrainian cities and “significant territories” or launch actions short of a full-scale invasion.

There was also the possibility of “coercive acts or provocative political acts" like the recognition of breakaway territories inside Ukraine.

“While we don't believe that President Putin has made a final decision to use these forces against Ukraine, he clearly now has the capability. And there are multiple options available to him,” Austin told a Pentagon news conference, urging the Russian leader to de-escalate the tensions.

On Thursday, US President Joe Biden told Zelenskyy in a phone call there was "a distinct possibility that the Russians could invade Ukraine in February," according to White House National Security Council spokesperson Emily Horne.

She reiterated Biden's recent warnings as tensions mount over Russia's buildup of troops on Ukraine's border. Kremlin spokesman Dmitry Peskov told reporters on Thursday that the response from the US — and a similar one from NATO — left “little ground for optimism”.

But he added that “there always are prospects for continuing a dialogue, it’s in the interests of both us and the Americans”.

Also speaking on Thursday, Sergei Lavrov said the US response to Russia's security demands contained some elements that could lead to “the start of a serious talk on secondary issues," but emphasized that “the document contains no positive response on the main issue.”

The key demands from Moscow are that NATO do not expand and that the alliance refrain from deploying weapons that might threaten Russia.

Peskov said that Putin and Biden will decide whether they need to have another conversation following two calls last month.

The US Secretary of State said Washington had made no concessions to the main Russian demands over Ukraine and NATO in a written response delivered to Moscow on Wednesday.

Antony Blinken added that the US proposals offered Russia a "serious diplomatic path forward". These included safeguarding the right of nations to choose their own alliances.

In formal proposals issued in December, Russia demanded guarantees that NATO halt its eastward expansion, rule out membership for Ukraine and other former Soviet countries, and roll back its military deployments in Central and Eastern Europe.

Ukraine’s Foreign Minister Dmytro Kuleba said Keiv had seen the US response before it was delivered to Russia and had no objections. He tweeted it was “important that the US remains in close contact with Ukraine before and after all contacts with Russia”.

On a visit to Denmark, Kuleba emphasized his country’s need to strengthen its defenses.

“This crisis is a moment of truth, and this is why we speak about weapons,” he said. “This is why we speak about economic sanctions. This is why we speak about the consolidated position of all of us, so that President Putin sees that there are no weak links in our defensive chain.”

Germany’s Foreign Minister Annalena Baerbock said during a parliamentary debate on Ukraine that her government is closely coordinating its policy with allies and considering a range of options that could include the new Nord Stream 2 Russian gas pipeline to Germany.

Russia has launched a series of military drills involving motorized infantry and artillery units in southwestern Russia, warplanes in Kaliningrad on the Baltic Sea, dozens of warships in the Black Sea and the Arctic, and Russian fighter jets and paratroopers in Belarus.

NATO said it was bolstering its deterrence in the Baltic Sea region, and the US ordered 8,500 troops on higher alert for potential deployment to Europe.

Meanwhile, Biden and new German Chancellor Olaf Scholz will discuss Russian aggression toward Ukraine during a Feb. 7 meeting in Washington, the White House announced on Thursday.

The one-on-one session will be Scholz's first Oval Office meeting since he took over leadership of his country in December following the 16-year tenure of Angela Merkel.

Germany’s refusal to join the US and other NATO members in providing weapons to Ukraine has annoyed some allies and raised questions about Berlin’s resolve in standing up to Russia.

Experts say Germany’s position is partly rooted in its history of aggression during the 20th century. Germany’s own militarization in Europe during two World Wars has led German leaders through the years to view any military response as a last resort.

Meanwhile, German officials also expressed regret that Russia has suspended mutual military inspections at a time of heightened tensions.

They are intended as confidence-building measures among members of the Organization for Security and Cooperation in Europe, or OSCE. A Foreign Ministry spokesman said Russia recently announced it would suspend the inspections until the end of February, citing the spread of the omicron variant.

In a break from the past, the US and its allies are increasingly revealing their intelligence findings, looking to expose Putin’s plans on Ukraine and deflect his efforts to shape world opinion.

The White House in recent weeks publicized what it said was a Russian “false-flag” operation to create a pretext for an invasion. Britain named Ukrainians it accused of having ties to Russian intelligence officers plotting to overthrow Zelenskyy.

The US also released a map of Russian military positions and detailed how officials believe Russia will try to attack Ukraine with as many as 175,000 troops.

But the release of information is not without risks. Intelligence assessments carry varying degrees of certainty, and beyond offering photos of troop movements, the US and its allies have provided little other proof.

Moscow has invoked past American intelligence failures, including false information put forward about Iraq’s weapons programs. — Euronews
