Seeking to build trust and understanding, India and China today discussed all aspects of bilateral relations with an aim of looking at ways to address irritants such as boundary question and other issues.

External Affairs Minister S M Krishna and his Chinese counterpart Yang Jiechi met here for about 90 minutes during which the Indian side is understood to have voiced concern over reported construction of a dam on Brahmaputra river by China, issuance of visas by China to Kashmiris on loose sheets of papers instead of passports and Chinese participation in projects in Pakistan occupied Kashmir (PoK).

The two sides also looked at ways to step up trade and investment and cooperation on climate change.

"I had a warm meeting Chinese foreign minister for over 90 minutes. We had fruitful exchange of views on all aspects of bilateral relations," Krishna said in a statement.

"We both see this (meeting) as part of building trust and understanding at political level," Krishna said.

The meeting between Krishna and Yang came two days after Prime Minister Manmohan Singh had an interaction with Premier Wen Jiabao in Thailand and agreed not to allow differences to impede development of bilateral relations.

Krishna said that he and Yang welcomed the "positive outcome" of meeting between the two Prime Ministers.

Krishna said that the two Ministers discussed how to further develop relations in the light of meeting between the two Prime Ministers.

The Prime Ministers of the two countries, who met in Thailand on the sidelines of ASEAN-India and East Asia Summits, sought to put behind the recent irritants as they agreed to "strengthen efforts to build political trust and understanding."

Krishna said that the two sides agreed on the importance of further developing high-level exchanges enhancing trade and economic cooperation, progressing defence contacts.

Yang invited Krishna to visit China next year, which was accepted. Dates for the visit will be worked out through diplomatic channels.

"Overall, I am indeed satisfied with my talks with the foreign minister today," Krishna said.

He said India and China will be celebrating in a befitting manner next year the 60th anniversary of establishment of diplomatic relations between the two countries.

The last few months have witnessed war of words between India and China over Arunachal Pradesh and Tibetan spiritual leader the Dalai Lama.

India has also objected to Chinese visas to Kashmiris being issued on loose sheets of paper instead of on passports, an apparent suggestion that the state is disputed.

New Delhi is also unhappy over Chinese participation in infrastructure projects in Pakistan-occupied Kashmir and has voiced opposition to construction of a dam by China on Brahmaputra river.
