Global stock markets surged Thursday after President Donald Trump was acquitted in an impeachment trial and China announced a tariff cut on U.S. imports and aid to businesses reeling from a virus outbreak.

London and Frankfurt opened higher, while Tokyo, Hong Kong and Seoul rose more than 2%.

Markets also were boosted by strong U.S. corporate earnings. That helped to dampen fears about the impact of sweeping Chinese efforts to contain a viral disease that closed factories, restaurants and shops as the death toll rose.
