SINGAPORE, June 6 (Reuters) - Shanghai copper slipped to a two-year low on Thursday, tracking falls in London's previous session, amid mounting concerns on weak metals demand due to rising trade tensions.
The most-traded copper contract on the Shanghai Futures Exchange fell as much as 1.3% to 45,860 yuan ($6,632.44) a tonne, its lowest since June 2017, and was down 1% at close.
The benchmark London copper contract rose 0.1% to $5,813 a tonne at 0709 GMT, struggling to bounce back strongly from a five-month low. The contract has lost around 9% since the beginning of May when the U.S.-China trade talks faltered.
"While we see some dynamics supporting a copper price recovery, short-term bearish sentiment should continue to affect copper prices," said analyst Helen Lau of Argonaut Securities.
