Oil prices edged lower on Friday after US inventory data showed lacklustre fuel demand in the world’s largest oil consumer while worsening US-China tensions weighed on global financial markets.

Brent crude LCOc1 slipped 36 cents, or 1%, to $34.93 a barrel by 0106 GMT and US West Texas Intermediate crude CLc1 was at $33.20 a barrel, down 51 cents, or 1.5%. Still, both contracts are set for a fifth weekly gain, helped by production cuts and optimism about demand recovery in other countries.

Thursday’s data from the Energy Information Administration showed that US crude oil and distillate inventories rose sharply last week. Fuel demand remained slack even as various states lifted travel restrictions they had imposed to curb the coronavirus pandemic, analysts said.

“Memorial Day weekend did not bring US motorists out in droves like many market bulls were hoping,” RBC Capital Markets analyst Christopher Louney said in a note.

Looking ahead, traders will be focusing on the outcome of talks on output cuts between members of OPEC+, the Organization of the Petroleum Exporting Countries (OPEC) and allies including Russia, in the second week of June.

Saudi Arabia and some OPEC members are considering extending record production cuts of 9.7 million barrels per day beyond June, but have yet to win support from Russia.
