SINGAPORE, Oct 30 (Reuters) - Copper prices in London fell on Wednesday as a possible delay in the trade deal between the United States and China weighed on sentiment.
The metal is often used as a gauge of global economic health. A prolonged trade dispute between the world's two biggest economies has hurt economic growth and demand for copper.
Three-month copper on the London Metal Exchange (LME) dipped 0.3% to $5,911 a tonne by 0239 GMT, while the most-traded copper contract on the Shanghai Futures Exchange edged up 0.1% to 47,480 yuan ($6,722.26) a tonne.
An interim trade agreement between the United States and China might not be completed in time for signing in Chile next month as expected, a U.S. administration official said, but stressing that does not mean the accord is falling apart.

* CHINA: China's three biggest commodities exchanges said on Tuesday they would end their practice of double-counting trades from Jan. 1, 2020 and report on a single-count basis instead to help them converge with international standards.
* "The China Securities Regulatory Commission is aligning the Chinese futures markets with international norms, and (this) is an example of a small step in the continuous process of reform and opening up," said John Browning, managing director of brokerage Bands Financial in Shanghai.
