Biden: Russia Risks More Isolation Over Ukraine Aggression

U.S. Vice-President Joe Biden warned on a visit to Kiev Friday that Russia risked further isolation over its "unacceptable" aggression in Ukraine.

"It's simply unacceptable in the 21st century for countries to attempt to redraw borders by force... because they don't like a decision their neighbor has made," he said after meeting Ukrainian President Petro Poroshenko.

He warned that Russia had failed to fulfill its commitments under agreements struck in September, adding: "So long as that continues, Russia will face rising costs, greater isolation."

Earlier on Friday, Biden met Ukraine's leaders as the ex-Soviet country marks a year since the start of protests that toppled a pro-Russian regime and sparked the conflict ravaging the nation's east.

The Ukrainian government hopes Biden will announce further U.S. assistance for its forces, locked in a drawn-out struggle with pro-Moscow separatists in the east.

Biden made no direct mention of increasing assistance to Ukraine during the press conference.

But a statement from his office said that the White House was pledging a further $20 million (16 million euros) to support reforms in law enforcement and justice, plus $3 million more for food rations and displaced people.

That brings to nearly $320 million it has committed this year.

The U.S. has so far limited its support to non-lethal security assistance but Kiev wants it to go further and offer weapons and ammunition.

Russia, which denies providing military support to the rebels, has warned that if the U.S. were to arm Ukrainian forces, the conflict in eastern Ukraine "will grow".

In Kiev, dozens of people gathered at the iconic Independence Square, known locally as Maidan, laying flowers at shrines to the more than 100 people who died in protests that started on November 21 last year.

Some mourners wept or crossed themselves as they remembered the dead while others said fresh protests were needed to bring real change to Ukraine, where corruption is rife.

Petro Runkiv, a 58-year-old civil engineer, left his wife, children and grandchildren in western Ukraine to join the protests last year.

"Of course, we are disappointed. Nothing changed," he said. "We need reforms and we are here to let our government know that we are ready for one more Maidan."

Student Angelika Valkova, 19, added: "The world doesn't care about us. We hear about U.S. military help for more than two months. Where is it?"

The protests started last year after then president Viktor Yanukovych suddenly scrapped a deal for closer ties with Europe.

They eventually led to his ousting in February which prompted Moscow to seize Ukraine's Crimea peninsula and later triggered separatist unrest in the industrial east which has killed more than 4,300 people since mid-April.

Poroshenko has declared Friday a "Day of Dignity and Freedom" and a series of memorial ceremonies are planned.

Poroshenko was heckled by relatives of the Maidan dead shouting "Shame!" over authorities' failure to convict anyone in connection with the deaths when he laid a candle at the shrines Friday.

He and Biden had been due to lay a wreath at the memorials together but instead met up nearby and shook hands before the U.S. vice president went into a meeting with Prime Minister Arseniy Yatsenyuk.

Biden also will meet Poroshenko before they issue a joint statement.

During his visit, the U.S. vice president is expected to try to shore up a tattered ceasefire in the east, which has been in place since September 5 but failed to prevent almost 1,000 people from dying in fighting since, according to the United Nations.

One more Ukrainian soldier and two civilians were killed in the region in the last 24 hours, Ukrainian security officials said Friday.

Yatsenyuk said Thursday he hoped for an announcement on further U.S. assistance to Ukraine during Biden's visit following a $53 million (42 million euro) package announced in September, which included $46 million of security assistance.

That included non-lethal military equipment such as night vision goggles, body armor and radios. But Kiev wants Washington to provide lethal assistance.

Pentagon spokesman Rear Admiral John Kirby told reporters Thursday that the U.S. was "still focused on non-lethal assistance right now".

Russia has warned against the U.S. arming Ukrainian forces, with the secretary of Russia's national security council, Nikolai Patrushev, saying the conflict in eastern Ukraine "will grow" if this happened.

The Kremlin denies Western and Ukrainian accusations that it is backing the rebels with troops and military equipment, but diplomatic relations have plunged to a low not seen since the Cold War over the seven-month conflict.

In an interview with Kiev's The Day newspaper published Thursday, Biden stressed there was "no military solution to this crisis" and accused Russia of "interfering in the affairs of a sovereign state".

He added: "I will be bringing a strong message of support to the Ukrainian people and government."
