The Myanmar-China natural gas pipeline started deliveries on Sunday after three years of construction, helping to diversify the country's energy import channels.

The 793-kilometer pipeline starts at Kyaukpyu on Myanmar's western coast and enters southwestern China at Ruili in Yunnan province.

The owner of the pipeline, PetroChina, said a parallel oil pipeline, expected to deliver oil by the end of this year, is 94 percent complete.
