The sources claimed that the Centre had agreed to hold talks on the issue with the UNC on August 29, 30 or 31, according to the convenience of the Naga outfit.
A representative from the Manipur government was also likely to attend the meeting, the sources said.
The UNC had called the economic blockade to press their demand for an "alternative arrangement" for Nagas in Manipur as they wanted to "dissociate itself" from the Manipur government.
Official sources said buses and trucks with essential items were plying on the national highways with security escort vehicles.
