With the summit, the seven-member grouping founded in Dhaka in 1985 steps into its third decade.
Dhaka hopes the summit in Bangladesh will mark a watershed that sees the much-criticised grouping begin to deliver concrete results for the region's 1.4 billion people.
SAARC, founded at a summit in Dhaka in 1985, groups Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan and Sri Lanka.
Although it was set up amid high hopes of reducing poverty and fostering amity, peace and stability, critics say two decades of squabbling and mistrust has resulted in it falling short of its potential.
Will the third decade bring about a change?
