(2) Data released Wednesday presented a mixed bag for China's economy, which hit an official growth target for the year but has failed to shake off several of the problems most persistently weighing on domestic demand and confidence.

(3) Federal Reserve Governor Christopher Waller says the US central bank should take a cautious and systematic approach when it begins cutting interest rates, a process that can start this year absent a rebound in inflation.

(4) Rishi Sunak suffered a major setback as a right-wing politician whom he made deputy chairman of the governing Conservative Party to boost support ahead of a looming UK general election resigned over the prime minister's refusal to toughen his signature anti-immigration bill.

(5) Zelenskiy turns on Davos charm with humor, handshakes and hugs. The Ukrainian president spent 24 hours pitching the Wall Street elite for investment and patching up ties with old allies as part of a push to shore up the faltering war effort.
