Geelani has been called for a meeting on August 24 with Aziz, who will be here for talks with Indian NSA Ajit Doval, while moderate separatist leaders have been invited for a reception being hosted by the High Commission in New Delhi for the visiting Pakistani official on August 23.
Aziz is expected to arrive in New Delhi on August 23 for the talks.
Geelani, the leader of hardline faction of Hurriyat who had boycotted the Eid Milan programme hosted by the High Commissioner Abdul Basit last month, will be travelling to Delhi for the meeting.
"Chairman Syed Ali Shah Geelani has been invited for talks with Pakistan NSA Sartaj Aziz. He will be travelling for the meeting," spokesman of his Hurriyat Ayaz Akbar told PTI.
Geelani had boycotted the Eid Milan programme on July 21 in protest against non-inclusion of Kashmir in the talks between Prime Minister Narendra Modi and his Pakistan counterpart Nawaz Sharif in Ufa, Russia, on July 10.
Mirwaiz Umar Farooq told PTI that he along with other leaders would be attending the reception being hosted for Aziz and urged political parties, especially the Congress, not to politicise the issue of his attending a function at the High Commission.
In August last year, India had cancelled Foreign Secretary-level talks with Pakistan after its envoy invited separatist leaders for consultations ahead of the meeting in Islamabad.
