New Delhi, Sep 11 (PTI) Noting that NAM countries faced common challenges like terrorism, Prime Minister Manmohan Singh today said mutual support and solidarity among its 116 members is of prime importance to deal with these, as he left for a tour of Brazil and Cuba to attend the IBSA and NAM summits.

Singh, who is expected to meet Pakistan President Pervez Musharraf in Havana on the sidelines of the NAM Summit, said he looked forward to "fruitful interactions" with a number of leaders from the developing world during his nine-day trip.

The Prime Minister is expected to convey India's concerns over continued cross-border terrorism to Musharraf and ask him to act in a "substantive" manner to eliminate the scourge.

Referring to the NAM as a "great movement", Singh told reporters here as a founding member, India will play its part in "helping NAM to revitalise itself so as to pursue the shared interests of its member states in a transformed world." "Mutual support and solidarity among NAM members is of prime importance as we confront several common challenges such as making globalisation more inclusive, the scourge of terrorism and addressing widespread hunger, poverty and disease," he said before leaving for Brasilia on his first leg of the tour.
