May 29 (Reuters) - London copper prices edged higher on Thursday, buoyed by upbeat market sentiment after a U.S. federal court blocked President Donald Trump's "Liberation Day" tariffs from going into effect, although a stronger dollar kept gains in check.
Three-month copper on the London Metal Exchange CMCU3 rose 0.2% to $9,577.50 per metric ton, as of 0151 GMT.
The most-traded copper contract on the Shanghai Futures Exchange (SHFE) SCFcv1 was steady at 78,010 yuan ($10,829.01)per ton.
A U.S. trade court on Wednesday blocked Trump's tariffs from going into effect in a sweeping ruling that the president overstepped his authority by imposing across-the-board duties on imports from nations that sell more to the United States than they buy.
This boosted risk sentiment in the wider financial markets, while also triggering a surge in the U.S. dollar index .DXY, which rose to highest level in more than a week. MKTS/GLOB
