"The US, India, and Japan can offer alternative options for economic connectivity that can compete and possibly even cooperate with China's Belt and Road Initiative, where appropriate," said Manpreet Singh Anand, who served as deputy assistant secretary of state for South and Central Asia in the previous Obama administration.
Now a distinguished professor of practice at the prestigious National Defence University, Anand said each of these countries India, Japan and US -- can bring various resources and expertise in the forms of private sector investment, clear and transparent rules of commerce, experience with large infrastructure projects, technology and innovative approaches that can create game changing effects.
Ken Weinstein, president of the prestigious Hudson Institute, said India-US-Japan trilateral has been a major focus of the work of the top American think-tank.
"The subject of US-India-Japan trilateral relations is one near and dear to our hearts at Hudson Institute," he said.

In his keynote address then, Abe talked about the need to grow closer US-Japan-India ties "to work together more closely not just in the area of trade and development but also on security policies to meet the challenge of a rising China and the various challenges that pose and the need to promote a rules-based order and stable rise of China and a rules-based Asia Pacific region open to trade," Weinstein said.
Having just returned from Tokyo last week, Weinstein said he met with senior Japanese officials "who were quite excited about the increased Japan-India defence trade and the increased defence cooperation that is going on between our three nations," he said.
Japanese officials, he said, "see it as fundamental to the future of the Indo-Pacific region, a vision that President Donald Trump is outlining on his trip through Asia now".
Satu Limaye from the East West Centre said Trump is carrying on from his predecessors on one-core continuity which is building US-Japan-India trilateral relations.
Optimistic about the structural requirement for this relationship, Limaye said whatever political changes occur in Tokyo, Delhi or Washington DC, the underlying driver of this relationship is going to continue.
"The fact that you have the third, second and tenth largest populations and the first, third and ninth largest economies - likely to get higher on the economic range as India grows - and democracies, is simply a symbolic and substantive reason that these three countries should cooperate. And the fact that they didn't so much before is again somewhat surprising," he said.
