Qatar has signed a 27-year deal to supply China’s Sinopec with LNG in what has been described as “the longest gas supply agreement in the history of the LNG industry”.

The deal will see QatarEnergy supply China’s largest oil conglomerate, with 4m tonnes per annum of LNG starting in 2026 in a deal estimated to be worth $60bn.

Under the terms of the sales and purchase agreement (SPA), the contracted LNG volumes will be supplied from QatarEnergy’s North Field East LNG expansion project.
