US promises security guarantees to Ukraine but will not send troops

"The president has been very clear. There are not going to be boots on the ground in Ukraine," the US Vice President said.

Vance added that the United States will continue to play an active role in offering Ukraine the security guarantees necessary to end the war.

"But we are going to continue to play an active role in trying to ensure that the Ukrainians have the security guarantees and the confidence they need to stop the war on their end and the Russians feel like they can bring the war to a conclusion on their end," he said.

Asked how involved Russia might be in providing these security guarantees, Vance said it is too early to say.

"First of all, we're not talking about security guarantees until after the war has come to a close. And, of course, the Russians are going to be a part of the conversation about bringing that war to a close. So, of course, they're going to have some stake in this," he added.

Earlier reports indicated that the US is prepared to take a limited role in providing Ukraine with security guarantees, including the possible deployment of pilots for air missions.

Russian demands on security guarantees

Russian Foreign Minister Sergey Lavrov has said that Moscow will not accept any collective security guarantees without its participation. He stressed that the Kremlin would demand veto rights and involvement from China.

Kyiv called these conditions unacceptable. The White House publicly mocked the proposal. The European Union also criticized it, with EU Commissioner Andrius Kubilius ridiculing both Lavrov and Russian leader Vladimir Putin.

Lavrov's suggestion that Russia, China, and the US could serve as security guarantors for Ukraine effectively derailed Moscow's negotiations with Washington.
