Several top Ukrainian officials were expected to be in Brussels on Wednesday for meetings with European national security advisers, President Volodymyr Zelenskyy said.

Economic and military pressures could force Russia’s hand. But its economy, though strained, is not strained enough to do that, analysts say. And President Vladimir V. Putin says Russia is winning the war.

The European Union on Wednesday revealed details of its plan to use billions of euros in frozen Russian assets to fund Ukraine's needs over the next two years, but Belgium rejected the scheme and insisted that it poses major financial and legal risks.

BRUSSELS, Dec 3 (Reuters) - The European Commission plans to make a legal proposal this week to use frozen Russian assets to fund Ukraine while also leaving open the possibility of borrowing on financial markets or mixing the two options, four sources told Reuters on Tuesday.

Meanwhile, Zelensky says some things "still need to be worked out" in the draft peace plan, but the US is taking "serious steps" to end the war.

Russia launched its largest barrage of drones and missiles in a month across Ukraine, killing at least three people, Ukrainian President Volodymyr Zelensky said Saturday, as a Kyiv delegation heads to the United States for fresh peace talks.

Oil prices rose on Wednesday, reversing earlier losses, as investors believe Russia-Ukraine peace talks are unlikely to lead to the removal of sanctions on Russian crude, though gains were limited by concerns about an overall supply surplus.

The foreign minister says the EU is downplaying its concerns and over the plan which Belgium sees as "fundamentally wrong".
