Oil prices rose on Tuesday ahead of an upcoming OPEC+ meeting on Sunday, in which analysts expect the group will not unwind remaining voluntary cuts.

Brent crude was up 72 cents, or 1.06%, at $68.87 a barrel by 11:07 a.m. EDT (1507 GMT).

U.S. West Texas Intermediate crude was at $65.34 a barrel, $1.33 or 2.08% higher. WTI futures did not settle on Monday due to the U.S. Labor Day holiday.

Investors will monitor a meeting of eight members of the Organization of the Petroleum Exporting Countries and their allies on September 7.

Analysts said they believed the group would not unwind the remaining voluntary cuts in place from the eight members, including Saudi Arabia and Russia, which were supporting the market and keeping prices in the $60 a barrel range.

OPEC+ might wait for more data after conclusion of the U.S. summer driving season before it makes its next move, independent analyst Gaurav Sharma said, given an expected supply surplus in the last quarter of the year.

Meanwhile, Saudi Aramco and Iraq's state oil company have stopped selling crude oil to India's Nayara Energy in the aftermath of sanctions imposed in July by the European Union on the Russian-backed refiner, three sources familiar with the matter said.

"The market is starting to wonder how that will impact flows. There is some concern about availability in the non-sanctioned pool of oil which may be becoming more dear supply wise, as there is going to be less opportunity to buy these grey market barrels if sanctions ratchet up," said John Kilduff, a partner at Again Capital.

Investors also considered the Shanghai Cooperation Organisation summit 2025, which took place from August 31 to September 1 and was attended by Chinese President Xi Jinping and Russian President Vladimir Putin, who pressed their vision for a new global security and economic order that prioritises the "Global South", in a direct challenge to the United States.

The two-day event was attended by more than 20 leaders of non-Western countries, including India's Narendra Modi, who is visiting China for the first time in seven years.

This conference may force U.S. President Donald Trump to react and could spur more secondary sanctions, especially on India, lending some support to oil prices according to Kilduff.

"This was an important conference that was not on everyone's radar as it should have been," Kilduff said.

Elsewhere, India is in talks with the U.S. for a bilateral trade agreement, India's trade minister Piyush Goyal said on Tuesday, days after Washington doubled tariffs on goods from India as a punitive measure for New Delhi's continued importation of Russian oil.

Expectations that U.S. data will show another crude draw were also boosting the market, UBS analyst Giovanni Staunovo said.

The U.S. summer driving season officially ended with Monday's Labor Day holiday, ending the highest demand period in the world's largest fuel market.

On the supply side, Ukrainian drone attacks have shut down facilities accounting for at least 17% of Russia's oil-processing capacity, or 1.1 million barrels per day, according to Reuters' calculations.
