Himachal Pradesh , Uttaranchal and Jammu and Kashmir will work out a joint strategy to force the Centre to have a separate policy for the promotion of tourism in hill states. Stating this at a press conference here today, the Himachal Pradesh Tourism Minister, Maj Vijay Mankotia, said the joint strategy would be finalised during a "conclave' being organised in collaboration with the Confederation of Indian Industries in September here. The Chief Ministers of the three states would participate in the conclave at which a comprehensive document would be prepared. It would be submitted to the Centre for making the necessary policy changes. He said Central support was essential for the development of the tourism industry in the hills. With the change of the political set-up at the Centre, more funds could be expected.
