GLOBAL MARKETS-Stocks rise with eyes on trade talks; pound rallies

* Pound up 1.9% vs USD; largest daily gain since March

* Oil prices rise as OPEC pledges decision on supply

* Copper jumps over 1.5%, gold slides (Updates to close, adds Trump comments after market close)

NEW YORK, Oct 10 (Reuters) - Stocks rose on Thursday after U.S. President Donald Trump said he would meet with China's top trade negotiator on Friday, while the British pound rallied after the prime ministers of Britain and Ireland revived hopes of a possible Brexit deal.

A drop in the U.S. currency, also tied to trade talks, supported dollar-denominated commodity prices, including oil, which rose after OPEC pledged to make a decision on supply in December.

Markets were expected to remain highly volatile as high-level U.S.-China trade negotiations were due to continue through Friday. Trump's comments after the close on Wall Street, calling negotiations "very, very good," sent S&P 500 futures higher.

The euro hit its highest since Sept. 20 versus the dollar as the greenback turned weaker across the board, partly due to a Bloomberg report about a U.S.-China currency pact to stop the yuan's devaluation. China's offshore yuan hit its strongest levels in more than two weeks.

Sterling jumped just shy of 2%, on track for its largest gain against the dollar in seven months, after Irish Prime Minister Leo Varadkar said a Brexit deal could be clinched by the end of October after what he called a very positive meeting with Boris Johnson.

The risk-on environment weighed on the greenback, and even harder on Japan's yen.

"With a Brexit deal looking more likely and U.S.-China talks showing more progress, it's just clear that the dollar is losing some safe-haven demand," said Juan Perez, senior currency trader at Tempus Inc in Washington.

The dollar index fell 0.4%, with the euro unchanged at $1.1004.

Sterling settled at $1.2440, up 1.9% on the day. The safe-haven yen suffered through a risk-on session and dropped 0.46% to the greenback at 107.96 per dollar.

TRADE THE TWEETS

Trump's tweet announcing his Friday meeting with Liu gave "market participants a reason to believe that perhaps a trade deal or at least a partial trade deal might be announced as early as tomorrow," said Robert Pavlik chief investment strategist at SlateStone Wealth LLC in New York.

Separately, Chinese state news agency Xinhua reported Liu said Beijing was willing to reach an agreement with Washington to prevent any further escalation of the trade war.

The Dow Jones Industrial Average rose 150.66 points, or 0.57%, to 26,496.67, the S&P 500 gained 18.73 points, or 0.64%, to 2,938.13 and the Nasdaq Composite added 47.04 points, or 0.6%, to 7,950.78.

The pan-European STOXX600 index rose 0.65% and MSCI's gauge of stocks across the globe gained 0.56%.

Emerging market stocks rose 0.35%. MSCI's broadest index of Asia-Pacific shares outside Japan closed 0.17% higher, while Nikkei futures rose 0.74%.

Treasury yields also rose on hopes of a trade resolution between the United States and China. However, some investors highlighted the difficulty of using the rapidly shifting headlines on trade to direct investment strategy.

"A choppy overnight session driven by conflicting signals regarding trade negotiations highlights the difficulty in chasing every 5 basis point move in yields, in that the proximate justification can unwind just as quickly," said Ian Lyngen, head of U.S. rates strategy at BMO Capital Markets.

Benchmark 10-year notes last fell 24/32 in price to yield 1.6698%, from 1.587% late on Wednesday.

The two-year note

Safe-haven gold fell; spot gold dropped 0.8% to $1,493.85 an ounce.

Copper posted its largest daily gain in a month, up 1.70% to $5,780.50 a tonne.
