Stock markets advanced on Tuesday following news that Donald Trump plans to spare automakers from some of his wide-ranging tariffs, boosting hopes of a less combative approach to his trade war.
Signs of easing trade tensions are also spurring sentiment, as governments line up to negotiate deals with Washington to avert the full force of sweeping tariffs.
"On tariffs, the latest newsflow was actually fairly positive at face value, as US officials continued to sound optimistic about potential trade deals," said Deutsche Bank managing director Jim Reid.
"The rhetoric from the administration is still pointing towards negotiations, rather than further escalation," he added.
European markets also reacted to a wave of first-quarter company earnings, with investors closely watching for signs of how tariffs are impacting business outlooks.
Frankfurt rose 0.5 percent and London advanced 0.2 percent. Paris, however, slipped.
Market sentiment was buoyed after the Wall Street Journal reported that the White House will spare automakers -- already facing 25-percent tariffs -- from further levies, such as those on steel and aluminium.
