SINGAPORE, Oct 10 (Reuters) - Middle East crude benchmark spot premiums of Oman, Dubai and Murban declined on Friday, weighed down by ample supplies and signs of soft buying in China.

Saudi Arabia's crude oil exports to China are set to fall in November to about 40 million barrels as refiners are expected to switch to cheaper spot supply from other Middle East producers, several sources with knowledge of the matter said on Friday.

That would be down from the expected surge of 51 million barrels of crude exports in October from the world's top oil exporter to the world's top importer.

In addition to OPEC+ raising its output since April, more exports from Russia also weighed on the Middle Eastern market, traders said.

Cash Dubai's premium to swaps fell 32 cents to $0.81 a barrel.

PetroChina will deliver a December-loading Dubai crude cargo to Mitsui following the deals.

Sanctions are clearly hurting the Russian economy but U.S. President Donald Trump is keeping his allies guessing whether he will sign off on more measures, despite Washington being party to the G7's deal to coordinate steps against the Kremlin, the EU's sanctions chief told Reuters.

Since late August, two or three trains of 50 tanker cars have been shipping fuel each day from Nayara Energy's refinery on the coast of western India to inland depots - more than double its previous usage of railways to move diesel and petrol.

The U.S. imposed sanctions on about 100 individuals, entities and vessels, including a Chinese independent refinery and terminal, that helped Iran's oil and petrochemicals trade, the administration of President Donald Trump said on Thursday.

The U.S. government has granted an authorization for energy major Shell SHEL.L and Trinidad and Tobago to develop an offshore gas field in Venezuela close to the maritime border, Trinidad's attorney general said on Thursday.
