During the 2017 ASEAN Summits in Manila, all four former members led by Abe, Australian Prime Minister Malcolm Turnbull, Indian Prime Minister Narendra Modi, and US President Donald Trump agreed to revive the quadrilateral alliance in order to counter China militarily and diplomatically in the Indo-Pacific region, particularly in the South China Sea. Tensions between Quad members and China have led to fears of what was dubbed by some commentators "a new Cold War" in the region, and the Chinese government responded to the Quadrilateral dialogue by issuing formal diplomatic protests to its members, calling it "Asian NATO"; Indian Foreign Minister S. Jaishankar denies China's allegations and claimed India never had ‘NATO mentality’.
