Modi-Xi informal summit in Chennai, Mahabalipuram: Calling the informal summit a "good idea", Chinese President Xi Jinping said he had a "heart to heart" conversation with PM Modi on the issue of bilateral ties.
Tsai made the trip in the midst of a protracted trade dispute between China and the United States, and just a few days after the Defense Department approved a $2 billion arms sale to Taiwan, a deal that China regards as provocative.
The truce offered relief from a nearly year-long dispute in which the countries have slapped tariffs on billions of dollars of each other's imports, disrupting global supply lines, roiling markets and dragging on global economic growth.
China is the North's only major ally and Xi Jinping's visit is aimed at bolstering the isolated country against pressure from UN sanctions over its nuclear and missile programmes and a breakdown in denuclearisation talks with the United States.
Modi will leave for a five-day visit to the South American nation on Wednesday, Foreign Secretary Vijay Gokhale told the media. He said Modi will hold bilateral meetings with several world leaders during the event, and return on December 2.
