A strategic communication on profound global changes, an in-depth discussion on long-term issues. That's how State Councilor and Foreign Minister Wang Yi described Indian Prime Minister Narendra Modi's trip to China. Saturday marked the final day of the ice-breaking trip, and both Xi Jinping and Modi agreed to strengthen communication and seek better ties. CGTN's ZHENG CHUNYING has the story.

The first ever informal visit by an Indian prime minister since 1988.

Free of any diplomatic frills.

The leaders of the world's two largest developing countries took a stroll by the East Lake in the central Chinese city of Wuhan.

They went on an hour-long boat ride, and appreciated the deep history of their ancient cultures during a personal tour in the city's museum.

Looking to the future, the two leaders underscored the importance of maintaining peace and tranquility in the border regions.

VIJAY GOKHALE INDIAN FOREIGN SECRETARY "They decided that they will strengthen communication between the two militaries in order to build trust and understanding."

President Xi Jinping said mutual trust is the basis for the stable development of bilateral relations.

Prime minister Modi also wrote about the meeting on Twitter, saying "Delighted to meet President Xi Jinping in Wuhan. Our talks were extensive and fruitful. We deliberated on stronger India-China relations as well as other global issues."

However, relations haven't been free of tensions. Last summer, more than 270 Indian troops crossed the boundary into China's Donglang area to obstruct infrastructure building.

The dispute was resolved when India withdrew their troops.

And some experts believe the timing of Modi's Wuhan trip is significant.

PROFESSOR SWARAN SINGH SCHOOL OF INTERNATIONAL STUDIES, JAWAHARLAL NEHRU UNIVERSITY "Especially now as the two leaders meeting, I think that context is defined by the fact that Donald Trump's America First, following the protectionist policies, focusing inwards. And that, I think, creates grounds for India and China to play a larger role."

Experts say the two countries are building a complementary relationship.

More evidence of that is likely to be on display when the two leaders meet again, at the summit of the Shanghai Cooperation Organization in June. ZHENG CHUNYING, CGTN.
