BEIJING, March 27 (Reuters) - Most base metals gained ground on Wednesday, with Shanghai zinc touching a more than one-year high, as investors focused on tight inventories and the resumption of U.S.-China trade talks.
The U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin are expected to arrive in Beijing later on Wednesday for talks aimed at resolving a long-running trade row that has weighed on metals prices.
With London Metal Exchange zinc stocks MZN-STOCKS falling to their lowest 28 years, the metal used to galvanise steel jumped 1.5 percent in London on Tuesday and prices in top zinc user China are also buoyant.
Current zinc ingot inventories are “extremely low” and the next two-three months will see “intense destocking” as consumption in China recovers, Jinrui Futures said in a note.
