US President Joe Biden has vowed Russia will never see victory in Ukraine, delivering a major speech in Warsaw hours after Vladimir Putin said Russia would continue its nearly year-long military offensive.
Putin, in his annual state-of-the-nation address Tuesday, accused the West of escalating the conflict and announced the Kremlin would suspend participation in the New START nuclear arms treaty with Washington.
Speaking hours later in the capital of NATO ally Poland, Biden pledged that "Ukraine will never be a victory for Russia -- never".
The 80-year-old leader had a day earlier made a surprise visit to Kyiv, his first since the invasion began and just days before the war's one-year anniversary.
Surrounded by a flag-waving crowd outside Warsaw's Royal Castle, Biden responded directly to Putin's accusations, saying the West "is not plotting to attack Russia".
He said Putin "thought autocrats like himself were tough" but faced the "iron will" of the United States and its partners."There should be no doubt: our support for Ukraine will not waver, NATO will not be divided and we will not tire."
Biden earlier met Polish President Andrzej Duda, saying his visit had come "at a critical moment".He also reaffirmed Washington's "iron-clad" commitment to NATO's principle of collective defence.Duda said that thanks to Biden "we can see that America can keep the world order".
China meanwhile said it was "deeply concerned" about the conflict, which it said was "intensifying and even getting out of control". Beijing has sought to position itself as a neutral party, while maintaining close ties with strategic ally Russia.
The Kremlin has said Wang may also meet Putin during his visit, according to the official TASS news agency.
Stoltenberg on Tuesday echoed US concerns that China could supply Russia with weapons to help it pursue its campaign in Ukraine.
The Western allies worry they are falling behind in supplying enough shells for Kyiv's artillery to fend off a renewed Russian offensive.
