India is free to join the Regional Comprehensive Economic Partnership, China's Vice Commerce Minister Wang Shouwen says, adding that it would boost trade between India and China which is growing "very fast".
The RCEP is the world's largest trade bloc backed by China and groups 15 Asia-Pacific economies, including Australia, Japan, New Zealand and 10 member-states of the Association of Southeast Asian Nations (ASEAN).
Relations have soured between the two nuclear-armed neighbours after clashes at a disputed border site in Ladakh in the western Himalayas resulted in the deaths of 20 Indian and four Chinese soldiers in June 2020.
Shouwen, speaking during a discussion at the Business 20 summit of G20 members in New Delhi, said it was India's decision whether to join the RCEP and that the door was "always open".
India's Trade Minister Piyush Goyal, who chaired the discussion, said trade between India and China is growing but "largely skewed in China's favour".
Prime Minister Narendra Modi spoke to China's President Xi Jinping about India's concerns over unresolved border issues on the sidelines of the BRICS summit in Johannesburg this week.
Both sides agreed to intensify efforts to disengage and de-escalate, India's foreign secretary told reporters on Thursday.
Xi told Modi that improving China-India relations served the interests of the two countries and was conducive to peace, stability, and development, according to China's official Xinhua news agency, which said the meeting was at Modi's request.
