METALS-Copper slips as dollar gains and China imports drop

* Dollar extends recovery on post-election relief

* China October copper imports fell, data shows (Updates with official midday prices)

LONDON, Nov 8 (Reuters) - Copper slipped on Thursday as the dollar extended its recovery after U.S. midterm elections, with prices also pressured by a drop in China's copper imports.

China, which consumes nearly half the world's copper, registered a 19 percent monthly drop in copper imports in October, data showed on Thursday.

Aanalysts, however, were not too downbeat about copper's prospects.

"There's a Golden Week effect in (the data). October data is usually lower. I would still expect relatively high refined copper imports over the fourth quarter because the import arbitrage has been wide open," said Colin Hamilton, head of commodities research at BMO Capital Markets.

The copper import data was part of a batch of China trade figures that showed much stronger than expected exports as shippers rushed goods to the United States to beat higher tariffs due to kick in at the start of next year.

Import growth also defied forecasts for a slowdown, suggesting that Beijing's growth-boosting measures to support the cooling economy could be starting to have an impact.

"Two or three weeks ago ... the feeling was that China wasn't reacting quickly enough to the weaker equity markets, but now we're getting better figures ... it should be supportive (of copper) in the short term," Hamilton said.
