"We are not trying to isolate any country. Pakistan is not linked graphically to Bay of Bengal and it is as simple as that," he said while addressing a press conference in Bangkok.
The Prime Minister was asked as if India was trying to isolate Pakistan in the seven-member regional grouping.
Meanwhile India today agreed to host the 2006 summit of Bimstec, a grouping of seven Asian countries, following a request from all the participants.
"At the request of all the participants, India agreed to host the next Bimstec summit in 2006," Prime Minister Manmohan Singh said, according to a news report received here from Bangkok.
He said between now and then, a lot of work was needed at senior official and ministerial levels.
In a bid to boost trade and investment in the region, India and six other Asian countries decided to take steps for timely completion of the area negotiations apart from introducing a special Bimstec.
At the first summit of Bimstec, Prime Minister Manmohan Singh along with leaders from Sri Lanka, Thailand, Bangladesh, Bhutan, Myanmar and Nepal signed a joint declaration, committing themselves to give a fillip to region co-operation by a slew of measures, including development of infrastructure.
Bimstec members decided to facilitate travel within the region for businesses, exchange programme and tourism through a business travel card or visa.
