US liquefied natural gas exporter NextDecade has reached an agreement to supply 1 million tonnes per annum of LNG from its Rio Grande facility to a subsidiary of China Gas Holdings.

The 20-year contract, which could start as early as 2027, would be supplied from the second train at Rio Grande LNG, which will be located near Brownsville, Texas. The LNG will be indexed to US Henry Hub prices and delivered on a free-on-board basis.
