CARACAS/WASHINGTON, (Reuters) – Venezuela’s President Nicolas Maduro, and Mexico’s opposition, are likely to announce a resumption in political negotiations with Mexico as Washington relaxes restrictions on Maduro’s highly sanctioned government.

The administration of President Joe Biden will soon authorize the U.S. Oil Company as early as Tuesday Chevron Corp (NYSE: ) is to begin negotiations with Maduro’s Government, temporarily lifting a U.S. ban. Two sources told Reuters.

Sources said that the U.S. has not yet made a decision on whether to renew Chevron’s limited Venezuelan operating license. Chevron remains the only U.S. oil company to have a presence in Venezuela. Venezuela is home to some of the most important crude oils reserves.

According to an American official, Chevron will have the right to meet with PDVSA and the government about the future plans for the Venezuelan company. This permit is required because U.S. sanctioned sanctions forbid any dealings or officials with PDVSA.

There are “guardrails” that prevent Chevron from allowing contacts with PDVSA. The opposition was consulted. Officials said that the U.S. steps were meant to make it easier for Mexico negotiations and are dependent on Maduro’s government being “constructive” during negotiations.

The official also stated that Washington has accepted to delist Erick Malpica (a former PDVSA official, and nephew of Venezuela’s first lady Cilia Flores) from the U.S. sanction list. According to an official, he had been removed from the list as he wasn’t part of the “regime structure”.
