After President Donald Trump threatened to impose "very severe" economic penalties against Vladimir Putin's Russia if he doesn't agree to a ceasefire in Ukraine within 50 days, the Trump administration has so far declined to provide many additional details about the consequences Russia will face or why he picked the deadline he chose.

Russian Foreign Minister Sergei Lavrov has listed Moscow's demands for a peace deal that would end its ongoing invasion of Ukraine, including Kyiv's demilitarization and neutrality, international recognition of territory occupied by Moscow, and the lifting of sanctions.
