Prime Minister Narendra Modi today became the first Indian Prime Minister since Indira Gandhi to visit Manila, the capital of Philippines in 36 years. Over the next three days, he will attend a summit of ASEAN or the Association of South-East Asian Nations, a 10-nation grouping besides India, that's expected to boost trade and defence cooperation. Before a gala dinner tonight to mark ASEAN's 50th anniversary, he had one-on-one meetings with US President Donald Trump and Chinese Premier Li Keqiang. The US is part of the Quadrilateral - a four-nation alliance including Japan, Australia and India - that is expected to be revived on the sidelines of the summit.
