National Security Adviser, Ajit Doval met with top Chinese diplomat Yang Jeichi in Shaghai ahead of Prime Minister Narendra Modi's visit to Qingdao for a summit of the Shanghai Cooperation Organisation.
The NSA's meet was bilateral and not part of the SCO arrangement. Doval's meeting with Yang, the Politburo member of the CPC, comes ahead of several key dialogues between the two countries, which are trying to reset the ties after the last year's 73-day long stand-off at Doka La.
The Indian Embassy in a brief statement said that Doval and Yang, both special representatives of the India-China boundary talks, held talks, but gave no details about the meeting.
Yang is also Director of Foreign Affairs Commission. Till last month, Yang was the State Councillor of the CPC, a top diplomatic post.
He was replaced by foreign minister Wang Yi. Wang will hold the dual posts of state councillor and foreign minister in a major reshuffle of top officials.
This is the second meeting between Doval and Yang after the Doka La standoff.
Yang attended the 20th round of boundary talks between the two countries in Delhi in December last year during which both sides decided to reset the ties with more interactions.
Since December, the two sides are trying to iron out differences on the China-Pakistan Economic Corridor, India's entry into the Nuclear Suppliers Group and China blocking the efforts to designate Jaish-e-Muhammad chief Masood Azhar as a terrorist by the UN.
The two countries are preparing for a series of high-level interactions leading up to Prime Minister Narendra Modi's proposed visit to the Shanghai Cooperation Organisation (SCO) summit in June.
External affairs minister Sushma Swaraj and defence minister Nirmala Sitharaman are scheduled to be in Beijing on 24 April to attend different meetings of the SCO and interact with their counterparts from the member states.
The eight-member SCO, in which India was the latest entrant along with Pakistan, is due to hold its summit in the Chinese city of Qingdao.
The SCO comprised of China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, Uzbekistan, India and Pakistan.
Ahead of the summit, the organisation which is focused on anti-terrorism cooperation is holding a host of ministerial and officials' meetings to work out a firm agenda for the summit to provide a new direction to the grouping.
SCO Foreign and Defence Ministers meetings are also scheduled on 24 April and almost around the same time, according to officials.
Both sides attach a lot of significance to these meetings to reset the ties as they were taking place after President Xi Jinping commenced his second-five-year tenure last month with the prospect of continuing in power for life following the removal of the two-term limit for the president.
