'China plus one' opportunity is opening up for India and Tamil Nadu is doing its best to take the state's competitive advantage in attracting foreign direct investments, former chief economic adviser Arvind Subramanian said on Thursday. Addressing an event organised by the Centre for Social and Economic Progress, Subramanian further said India was not able to attract FDI like China, Taiwan and Vietnam, due to which the domestic firms have not been able to integrate with global value chain. Not being part of the global value chain have adversely impacted our exports and labour-intensive sector, he said, adding that 'China plus one' opportunity is opening up for India and Tamil Nadu is doing its best to take its competitive advantage in attracting foreign direct investments.
