The gas pipeline will allow delivery of natural gas from Burma's offshore fields to China with an expected annual capacity of up to 12 bcm of natural gas. The pipeline will be supplied from the A-1 and A-3 Shwe oil field. China would start receiving natural gas from Burma's Shwe project through the pipeline in April 2013. The Shwe, Shwe-Phyu, and Mya areas in the A-1 and A-3 blocks, estimated to hold 127–218 bcm of natural gas in total, are operated by a group led by Daewoo International Corp. The operators group also includes Myanma Oil and Gas Enterprise, GAIL, and Korea Gas Corporation.
