Nepal has signed a deal with China to import petroleum products. The Himalayan nation tries to boost supplies to deal with a deepening fuel crisis. Kathmandu has been forced to ration fuel after protests against a new constitution. The Nepalese Embassy Wednesday said in a statement, a Memorandum of Understanding had been signed between Nepal Oil Corp and National United Oil Corp (PetroChina), without giving details of the deal. The statement said China would also supply one thousand tonnes of fuel to Nepal as a grant.
