SINGAPORE, March 5 (Reuters) - China ?has asked refiners to halt signing new contracts to export fuel and to try to cancel shipments already committed as tight oil supply due to the Iran war curbs refinery output, several people with knowledge of the matter said on Thursday.
The guidance does not apply to jet fuel refuelling for international flights, bonded bunkering or supplies to Hong Kong or Macau, the industry and trade sources said.
