SINGAPORE, May 1 (Reuters) - London prices for copper and most other metals rose on Wednesday, buoyed as trade talks aimed at ending a bitter trade war between China and the United states kicked off in Beijing.
U.S. Treasury Secretary Steven Mnuchin described a working dinner with China Vice Premier Liu He the night before the talks as "nice".
Trading was thin as May 1 is a holiday in many markets. The Shanghai Futures Exchange will remain closed for the rest of the week, reopening on Monday.
