LONDON, Nov 28 (Reuters) - Oil prices fell for a second day on Thursday after official data showed U.S. crude and gasoline stocks rose and President Donald Trump signed into law a bill backing protesters in Hong Kong, fuelling tensions with China.

Brent crude was down 32 cents, or 0.5%, at $63.74 a barrel by 1327 GMT.

West Texas Intermediate crude fell 18 cents, or 0.3%, to $57.93.

China warned the United States that it would take "firm countermeasures" in response to U.S. legislation backing anti-government protesters in Hong Kong.

Investors are concerned that the move might delay further a preliminary agreement between the United States and China to put an end to their trade war that has slowed global economic growth, and consequently consumption of oil.

"The approval of the Hong Kong legislation backing protesters is likely to put the trade agreement into question as China has reiterated its threat of retaliation," said Hussein Sayed, chief market strategist at FXTM.

"If investors suspect that the trade agreement is under real danger, expect to see a sharp sell-off in December. For now, investors are taking a wait-and-see approach."

Crude stockpiles in the United States swelled by 1.6 million barrels last week as production rose to a record 12.9 million barrels per day (bpd) and refinery runs slowed, the Energy Information Administration said.

Investors have also been focused on next week's meeting of the Organization of the Petroleum Exporting Countries and allies including Russia, a group known as OPEC+, which have been withholding production to support prices.

"We expect OPEC+ to roll over its current production-cut deal, which is set to expire at the end of March, by three to six months," UBS oil analyst Giovanni Staunovo said.

"The upshot is that deeper cuts by the entire membership are unlikely."

Russian oil companies proposed not to change their output quotas as part of the global deal until the end of March, putting pressure on OPEC+ to avoid any major policy change.

They also offered to exclude production of gas condensate, a light oil, from the output quotas as Russia has been struggling to meet its supply-reduction targets in recent months.

Easing supply concerns, Libya's National Oil Corporation (NOC) said facilities at the 70,000 bpd El Feel oilfield had suffered only minor damage in fighting over the past two days, allowing production to restart.
