Three-month copper on the London Metal Exchange was up 0.2% at $5,888 a tonne.

China will allow local governments to use proceeds from special bonds as capital for investment projects to support the economy, while U.S. President Donald Trump said he was holding up a trade deal with China until Beijing agrees to his points.
