World’s ‘Longest’ Gas Supply Deal Qatar and China signed the 27-year natural gas supply deal which will be the longest gas supply dead any country ever made. The China Petroleum and Chemical Corporation (Sinopec) will get 4 million tonnes of liquefied natural gas (LNG) annually from the state energy company’s new North Field East project. The deal marks the longest gas supply agreement in the history of the LNG industry. Since Russia invaded Ukraine, European nations have become more interested in Qatar’s gas, which is primarily sold to Asian nations led by China, Japan, and South Korea.
