The two-day conclave is likely to be attended by many foreign delegates and ministers from other state governments.
Saying that the conclave was being organised to promote tourism in the Buddhist Circuit, Usmani also instructed officials to ensure encroachment-free roads, clear of garbage and traffic congestion.
He also advised officials to invite officials from the ministry of tourism to ensure that preparations for the event were carried out smoothly.
The chief secretary added that at least 267 rooms should be booked in advance, to accommodate all the travelling dignitaries from within the country and outside.
