Chinese President Xi Jinping's upcoming trip to India and Nepal is expected to inject new impetus into China's relations with the two countries, an official said on Wednesday.

The Chinese Foreign Ministry announced earlier in the day that at the invitation of Indian Prime Minister Narendra Modi and Nepali President Bidhya Devi Bandari, President Xi will attend the second informal meeting with Modi and pay a state visit to Nepal from Oct. 11 to 13.

This will be Xi's first overseas trip after the grand celebration of the 70th anniversary of the founding of the People's Republic of China, Vice Foreign Minister Luo Zhaohui told a press briefing.

Xi's trip will inject new impetus into China-India and China-Nepal relations, even China's relations with South Asia, Luo said, adding that Xi's trip will also open up new space for strengthening regional connectivity and economic and trade cooperation, set up new platforms for enhancing mutual trust and friendship among regional people, and make new contributions to world peace and prosperity.

China and India, both as developing countries and emerging economies, are the only two major countries in the world with a population of more than 1 billion, Luo said, stressing that China-India cooperation will not only benefit the development of the two countries, but also help promote world multipolarization and economic globalization, and safeguard the common interests of developing countries.

Since the first informal meeting between Xi and Modi in Wuhan last year, China-India relations have entered a new stage of steady growth, with cooperation and exchanges being carried out in various fields and differences being properly managed, Luo said.

In Chennai, Xi will have an in-depth communication with Modi on issues that have overall, long-term and strategic significance on bilateral relations, set the tune and guide the direction for future development of the ties, and speak to the world in unanimous voice, so as to inject positive energy into the world full of uncertainties.

Regarding Xi's visit to Nepal, Luo said that Xi will be the first Chinese president to visit the South Asian country after an interval of 23 years.

Nepal, as a friendly neighbor, also serves as an important partner of China in terms of carrying out the Belt and Road cooperation, Luo said.

Since the establishment of diplomatic ties, the two countries have treated each other on an equal footing with mutual respect and support, said Luo, adding that China and Nepal have become a model of mutually beneficial cooperation between countries that are different in social system and size.

"This historic visit will definitely exert historic influence," Luo said.

He said that Xi will attend the welcome ceremony and banquet hosted by President Bandari, meet with Bandari, hold talks with Prime Minister K.P. Sharma Oli and jointly witness the signing of cooperation documents with him.

Xi will also meet with co-chairman of the Nepal Communist Party Pushpa Kamal Dahal, also known as Prachanda, and leaders of the country's Federal Parliament and other political party leaders, Luo added.

Leaders of the two countries will make new plans for the development of bilateral relations, ushering in a new era of fast development for China-Nepal relations, Luo said.

This will also consolidate political mutual trust and foundation of public opinions for friendship between the two countries, push forward high quality construction of the Belt and Road, speed up building an interconnectivity network across the Himalayas, and inject new impetus into pragmatic cooperation in various areas between the two countries, Luo said.
