SINGAPORE, Sept 24 (Reuters) - Vietnamese crude price differentials rose in Asia on Monday as firm refining margins and robust demand from Shell supported spot premiums for November cargoes. Shell has bought at least five cargoes of Malaysian and Vietnamese crude for November loading as it restarted last week a crude distillation unit (CDU) and a 35,000 bpd hydrocracker at its Singapore refinery after scheduled maintenance that began in mid-July. Yet, the oil major could re-sell some of its term cargoes such as Seria Light as the closure of its 79,000 barrels per day (bpd) Clyde refinery this month is expected to curb its demand, a trader said. * SELL TENDERS - Vietnam's PV Oil sold two 300,000-barrel cargoes of Te Giac Trang (TGT) crude to an oil major, likely Shell, at between $5.50 and $6 a barrel above dated Brent, up from a premium of $5.20 a barrel in the previous month. The cargoes will load on Nov. 6-10 and 11-15. - India's ONGC offered 700,000 barrels of Russian Sokol crude for loading on Dec. 1-4 in a tender to close on Sept. 26 with bids valid until a day later. - Petronas offered two 250,000-barrel cargoes of Muda condensate for loading on Nov. 1-7 and 23-29. It also offered 300,000 barrels of Cakerawala condensate for Nov. 19-28 loading. The tenders will close on Sept. 26 with bids valid until a day later. * BUY TENDERS - PV Oil issued a tender to buy crude for delivery on Nov. 20-30. Offers are due on Sept. 26 and will stay valid for 2 days. The Vietnamese marketer bought earlier this month a cargo of Champion crude for October-November delivery as it seeks imports to replace Bach Ho which has become too heavy to be processed at the Dung Quat refinery. - Taiwanese refiner CPC Corp bought nearly 3 million barrels of Angolan crude for November loading in a tender, a steady volume with the previous month, traders said. The state-owned company bought 1.9 million barrels of Cabinda and 950,000 barrels of Palanca crude that will be delivered in December, they said. Details of sellers and prices were not immediately available. - India's MRPL has bought 600,000 barrels of Libyan Mellitah condensate from Marubeni via tender, industry sources said. MRPL bought the November loading crude at a 50 cents a barrel premium to dated Brent on a free on board basis, the sources said. - Vietnam's NamViet Oil Refinery and Petrochemicals JSC is seeking 150,000 to 200,000 barrels of condensate for loading from Singapore or Vietnam in November. * MARKET NEWS - Leaders of Sudan and South Sudan met on late on Sunday to try reach a deal to end hostilities and restart oil exports but there was still no breakthrough on a key security accord after two weeks of talks in Ethiopia, officials said. - China's commercial crude inventories at the end of August eased for the first time in six months, the official Xinhua News Agency reported on Monday, as refineries raised production while scaling back on crude oil imports.
