Yesterday's key developments:

• US President Donald Trump said Sunday there was a"good chance" of a Russia-Ukraine deal following the latest US-Ukraine talks in Florida, but cautioned that a corruption scandal roiling Kyiv was not helpful.
• President Donald Trump's special envoy, Steve Witkoff, is scheduled to meet with Putin in Moscow in the next few days.
• US and Ukrainian negotiators held hours of what both sides called"productive" talks in Florida on Sunday on a plan Washington wants to form the basis of a peace deal between Russia and Ukraine.
