SINGAPORE, Oct 9 (Reuters) - Shanghai copper fell to its lowest in over a month on Wednesday as an expanding trade dispute between the United States and China intensified concerns over demand.
The most-traded November copper contract on the Shanghai Futures Exchange fell as much as 0.8% to 46,520 yuan ($6,515.68) a tonne, its lowest since Sept. 4, tracking overnight declines in the London market. It was down 0.5%, as of 0421 GMT.
The United States and China, the world's two biggest economies, are due to have their first minister-level talks in months on Thursday trying to end a 15-month long trade dispute that has hurt the global economy.
However, hopes of a resolution appeared low as Washington on Tuesday imposed visa restrictions on Chinese officials for the detention or abuse of Muslim minorities, angering Beijing.
"It has become a little bit difficult for the negotiation to continue or to progress to a desired stage. The market has already expected this resolution will take a long time," said analyst Helen Lau of Argonaut Securities.
China is the world's biggest copper user, accounting for about half of global copper demand.
