Washington, Aug 6 (AP) US President Donald Trump could meet in person with Russian President Vladimir Putin as soon as next week as he seeks to broker an end to the Russia-Ukraine war, a White House official said on Wednesday.

The official cautioned that a meeting has not been scheduled yet and no location has been determined. The official was not authorised to speak publicly and spoke to The Associated Press on condition of anonymity to discuss internal plans.

News of a potential meeting, which was first reported by The New York Times, came hours after Trump's special envoy Steve Witkoff met with Putin in Moscow on Wednesday. Trump had posted earlier on Truth Social that Witkoff "had a highly productive meeting" with Putin in which "great progress was made".

Trump said he updated America's allies in Europe about the meeting and that they will work toward an end to the Russia-Ukraine war "in the days and weeks to come".

White House press secretary Karoline Leavitt said, "The Russians expressed their desire to meet with President Trump, and the President is open to meeting with both President Putin and President Zelensky." Her statement did not address the potential timing of any meeting.

Witkoff met with Putin days before the White House's deadline for Russia to reach a peace deal with Ukraine or potentially face severe economic penalties that could also hit countries buying its oil.

The meeting between Putin and Witkoff lasted about three hours, the Kremlin said.

Putin's foreign affairs adviser Yuri Ushakov said Putin and Witkoff had a "useful and constructive conversation" that focussed on the Ukrainian crisis and, in a nod toward improving relations between Washington and Moscow, "prospects for possible development of strategic cooperation" between the United States and Russia.

The threat of US sanctions Earlier on Wednesday, the same White House official said the US was still expected to impose secondary sanctions against Russia on Friday, after a 10-day deadline that Trump imposed is to expire. The White House has not yet released details about the sanctions.

Washington has threatened "severe tariffs" and other economic penalties if the killing does not stop.

Trump also has threatened to slap tariffs on nations that buy Russian oil, which could increase import taxes dramatically on China and India. He said on Tuesday he had not publicly committed to any particular tariff rate, and indicated that his decision could depend on an outcome of the meeting with Putin.

Trump has expressed increasing frustration with Putin over Russia's escalating strikes on civilian areas of Ukraine, intended to erode morale and public appetite for the war. The intensified attacks have occurred even as Trump has urged the Russian leader in recent months to relent.

Zelenskyy said on Wednesday evening that he and Trump spoke on the phone after Witkoff met with Putin. He said "European leaders also participated in the conversation" and "we discussed what was said in Moscow".

"It seems that Russia is now more inclined to agree to a ceasefire," Zelenskyy said, adding that the pressure on Moscow "is working", without elaborating.

Zelenskyy stressed it was important to make sure Russia does not "deceive us or the United States" when it comes to "the details" of a potential agreement. Kyiv proposes that Ukraine and its allies soon "talk to determine our position, our common position, and our common view".

The fighting grinds on Overnight from Tuesday to Wednesday, Russian forces hit a recreational centre in Ukraine's southern Zaporizhzhia region, killing two people and injuring 12, including two children, regional Gov. Ivan Fedorov said on Wednesday.

Russian forces launched at least four strikes on the area and initially attacked with powerful glide bombs.

"There is zero military sense in this strike. Only cruelty to intimidate," Zelenskyy said in a post on Telegram.

Russia also struck the Ukrainian power grid and facilities for heating and cooking gas, Zelenskyy said, as Ukraine makes preparations for winter.

Western analysts and Ukrainian officials say Putin is stalling for time and avoiding serious negotiations while Russian forces push to capture more Ukraine land. A Russian offensive that started in the spring and is expected to continue through the fall is advancing faster than last year's push but is making only slow and costly gains and has been unable to take any major cities.

The situation on the front line is critical for Ukrainian forces but defences are not about to collapse, analysts say.

Risks of more pressure Stepping up diplomatic and economic pressure on the Kremlin risks stoking international tensions amid worsening Russia-US relations.

Putin has given no hint that he might be ready to make concessions. Instead, the Russian leader and senior Kremlin officials have talked up the country's military strength.

Putin announced last week that Russia's new hypersonic missile, which he says cannot be intercepted by current NATO air-defence systems, has entered service.

Russia announced on Tuesday that it no longer regards itself as bound by a self-imposed moratorium on the deployment of nuclear-capable intermediate range missiles, a warning that potentially sets the stage for a new arms race.

Former Russian President Dmitry Medvedev, meantime, warned that the Ukraine war could bring Russia and the US into armed conflict. Trump responded to that by ordering the repositioning of two US nuclear submarines.

Kremlin spokesman Dmitry Peskov on Monday welcomed Witkoff's visit. "We consider (talks with Witkoff) important, substantive and very useful," he said.

Trump initially gave Moscow a 50-day deadline, but later moved up his ultimatum as the Kremlin continued to bomb Ukrainian cities.

However, Trump himself doubted their effectiveness, saying on Sunday that Russia has proven to be "pretty good at avoiding sanctions".

"They are wily characters," he said of the Russians.

The Kremlin has insisted that international sanctions imposed since its February 2022 invasion of its neighbour have had a limited impact.

Ukraine maintains the sanctions are taking their toll on Moscow's war machine and wants Western allies to ramp them up. (AP) RC
