This was decided at a meeting of the council of ministers chaired by the Chief Minister Lal Thanhawla last evening.
The Manipur-based Hmar outfit had earlier expressed its desire to elevate the official-level talks to the political level.
Meanwhile, state Home Minister R Lalzirliana said ongoing parleys with HPC(D) would be resumed during August.
On the issue of extension of the bilateral Suspension of Operations signed on January 31 and scheduled to expire by tomorrow, Lalzirliana expressed that there would not be any hostilities during the few days gap.
HPC(D) is demanding a Hmar state consisting of the Hmar tribal people inhabited areas of Mizoram, Manipur and Assam.
