Even before the summit between the United States and Russia got underway on Wednesday, Ukrainian officials played down the prospect — however unlikely — for a breakthrough on one of the thornier issues on the agenda: ending the war in eastern Ukraine, the only active conflict in Europe today.
Ukraine said it would not accept any arrangements made in Geneva between President Biden and President Vladimir V. Putin on the war, which has been simmering for seven years between Russian-backed separatists and the Ukrainian Army, officials said.
The Ukrainian government has in recent years dug in its heels on a policy of rejecting any negotiation without a seat at the table after worry that Washington and Moscow would cut a deal in back-room talks. The approach has remained in place with the Biden administration.
“It is not possible to decide for Ukraine,” President Volodymyr Zelensky said on Monday. “So there will be no concrete result” in negotiations in Geneva, he said.
Ukraine’s foreign minister drove the point home again on Tuesday.
“We have made it very clear to our partners that no agreement on Ukraine reached without Ukraine will be recognized by us,” Dmytro Kuleba, the foreign minister, told journalists. Ukraine, he said, “will not accept any scenarios where they will try to force us to do something.”
Ukraine will have a chance for talks with the United States. Mr. Biden has invited Mr. Zelensky to a meeting in the White House in July, when a recent Russian troop buildup along the Ukrainian border is sure to be on the agenda.
Russia massed more than 100,000 troops along the Ukrainian border this spring. Despite an announcement in Moscow of a drawdown, both Ukrainian and Western governments say that only a few thousand soldiers have departed, leaving a lingering risk of a military escalation over the summer.
