The trend of diversification in global liquefied natural gas (LNG) supply is becoming increasingly evident, and Qatar's long-standing position as the largest supplier is also facing disruption. In the next few years, the LNG market will present a scene of "no longer unified, champions taking turns". Australia, which once surpassed Qatar at the end of last year, is just one step away from winning the championship, and it seems that the strong production increase of the United States is not difficult to squeeze out Australia. Obviously, the battle between Australia, the United States, and Canada over the "largest LNG supplier" has become increasingly intense.
