China National Offshore Oil Corp., the third-largest offshore oil producer in the country, said that it has signed deals for spot cargoes of liquefied natural gas with three foreign companies.

CNOOC said it had concluded master agreements with France's Total SA (TOT), Franco-Belgian supplier Suez (SZE) and a unit of Royal Dutch Shell PLC (RDSA). They were all signed between Oct. 5 and Oct. 10.

The prices and volumes will be determined by each shipment purchased by CNOOC under the terms of the master agreements, with the supply dates to be decided later.
