* U.S. crude inventories fall 12.6 million barrels in week - EIA
* U.S. stockpile draw is largest since Sept. 2016
* Trump threatens tariffs on another $200 bln of Chinese goods
* U.S. could also consider waivers on sanctions against Iran
* Libya lifts force majeure on four oil ports (Adds U.S. inventory data, updates prices, changes dateline to NEW YORK, previously LONDON)
NEW YORK, July 11 (Reuters) - Oil futures pared losses briefly Wednesday after U.S. crude inventories fell the most in nearly two years, before trading lower in a volatile session in which supplies from Libya and Iran were expected to increase.
U.S. crude stockpiles decreased by nearly 13 million barrels last week, while gasoline inventories also fell and distillate stockpiles rose, the Energy Information Administration said on Wednesday. The decrease was the biggest since Sept. 2, 2016. Crude benchmarks shrugged off the draw.
"In spite of the extraordinary draw in crude oil inventories, the market is under pressure after refiners produced a record amount of gasoline this week and in conjunction with a greater than expected build in distillate inventories," said Andrew Lipow, president at Lipow Oil Associates in Houston.
Brent crude fell $1.84 to $77.02 a barrel by 10:46 a.m. EDT (1446 GMT), after touching $77.84 a barrel after the data was released. Brent earlier touched a session low of $76.76 a barrel. U.S. light crude, supported by the tight North American market, was down 88 cents at $73.23 a barrel.
The specter of tariffs on a further $200 billion of Chinese goods sent commodities lower along with stock markets, as tension between the world's biggest economies intensified.
"Trade concerns have bitten today," said Michael McCarthy, chief markets strategist at CMC Markets. "If these tariffs are introduced there will be an impact on global growth and demand."
The price fall was aided by news Tripoli-based National Oil Corp (NOC) had lifted a force majeure on four Libyan oil ports, saying production and exports from the terminals would "return to normal levels in the next few hours."
Libyan oil production fell to 527,000 barrels per day (bpd) from a high of 1.28 million bpd in February following the port closures, the NOC said on Monday.
"The lifting of force majeure at all the Libyan ports will certainly come as relief from a supply perspective, but it remains to be seen how quickly exports can return to normal," Harry Tchilinguirian, head of oil strategy at BNP Paribas, told Reuters Global Oil Forum.
Adding to the bearish mood were signs of a possible relaxation of U.S. sanctions on Iranian crude exports.
U.S. Secretary of State Mike Pompeo said on Tuesday that Washington would consider requests from some countries to be exempt from sanctions due to go into effect in November to prevent Iran from exporting oil.
Washington had previously said countries must halt all imports of Iranian oil from Nov. 4 or face U.S. financial restrictions, with no exemptions.
The United States pulled out of a multinational deal in May to lift sanctions against Iran in return for curbs to Tehran's nuclear program.
The prospect of sanctions on oil exports from Iran, the world's fifth-biggest oil producer, has helped push up oil prices in recent weeks with both crude contracts trading near 3-1/2 year highs.
Supply to the U.S. market has also been squeezed by the loss of some Canadian oil production.
