China, the world's biggest copper user, said on Wednesday it would strengthen its management of commodity supply and demand to curb "unreasonable" increases in prices, and prevent them being passed on to consumers.
Benchmark copper on the London Metal Exchange (LME) broke above the previous record high of $10,190 set in 2011 and had gained 2.3% to $10,325.
The most-traded June copper contract on the Shanghai Futures Exchange climbed as much as 2.7% to 74,950 yuan ($11,603) a tonne, its highest since May 2006 and only 1.6% below its record peak of 76,160 yuan.
Benchmark copper on the London Metal Exchange was up 0.1% at $9,895 a tonne.
Copper prices dipped initially on Friday, but then joined gains in other risky assets such as world stocks, which held near record highs, lifted by strong US data and the Federal Reserve's vow to support the economy.
