Oil prices rose on Tuesday, settling at the highest in more than two years after the top U.S. diplomat said that even if the United States were to reach a nuclear deal with Iran, hundreds of U.S. sanctions on Tehran would remain in place.

That could mean additional Iranian oil supply would not be re-introduced into the market soon, Reuters reported.

Brent crude rose 73 cents, or 1%, to close at $72.22 a barrel, the highest it has settled since May 2019. U.S. West Texas Intermediate oil rose 82 cents, or 1.2%, to settle at $70.05 a barrel, highest since October 2018.

Barriers to the revival of Iran's nuclear deal remain ahead of talks due to resume this week between Tehran and world powers, four diplomats, two Iranian officials and two analysts told Reuters.
