But any breakthrough could be expected only after the April-May general election in India, he added.
"The composite dialogue is facing delays due to upcoming polls in India but groups handling trade‚ energy and the visa regime are conducting negotiations," he said.
"Back channel talks are continuing with India on the issues of Kashmir‚ Sir Creek and Siachen," he said.
Pakistan has appointed former Foreign Secretary Shehryar Khan as its point man for back channel talks and his Indian counterpart is former envoy S K Lambah. Now when India is heading for elections‚ peace on the Line of Control (LoC) and continuation of talks is necessary to avoid any tensions in bilateral relations, he added.
Aziz described the Kashmir dispute as a very important issue whose resolution is imperative for improving Pakistan-India relations.
Several countries had realized the importance of peace between the two sides and "are now evincing interest in the Kashmir dispute", he claimed.
Aziz further said Prime Minister Nawaz Sharif had invited his Indian counterpart Manmohan Singh to visit Pakistan. "Though there is less possibility of his visit, but if he wishes to visit Islamabad in the next few weeks‚ we will definitely welcome him," he said.
Singh on Friday expressed hope of visiting Pakistan in the next four months and said circumstances were "not appropriate" for a visit so far.
Pakistan is keen to resume the composite dialogue with India, which was called off after an Indian soldier was decapitated in January last year along the LoC.
