Sept 27 (Reuters) -Copper prices fell in London on Friday but were set for their best weekly gain in more than four months, on hopes of a rebound in demand for metals after Chinese officials pledged stimulus to boost the economy.

Three-month copper on the London Metal Exchange CMCU3 fell 0.2% to $10,062.50 per metric ton by 0319 GMT. On a weekly basis, the contract was up 6.4%, on track for its biggest gain since the week of May 13.

The most-traded November copper contract on the Shanghai Futures Exchange SCFcv1 climbed 2.1% to 79,020 yuan ($11,263.95) a ton. The contract was set for a third straight weekly gain.

Beijing rolled out a huge stimulus package and supportive measures this week to revive the economy, including lowering interest rates, injecting liquidity into banks, and potentially issuing special sovereign bonds worth more than $280 billion.

More fiscal measures are expected to be announced before China's week-long holidays starting on Oct. 1.

The premium to import copper into China stayed firm at $65 a ton, indicating solid demand from the world's top consumer of the metal.

However, China's industrial profits swung back to a sharp contraction in August for their biggest decline this year, partly due to a lack of demand.

The bleak data emphasised struggles in China's economy, but also firmed up the case for further stimulus, which in turn could boost metals futures prices.
