Phnom Penh, Jul 12, (PTI): Pakistan today said it is willing to go by the agreement that it had in the past with India to resolve some of the disputes like Sir Creek and Siachen.

"If you look at may be some of the disputes that we have. We have Sir Creek, we have Siachen... Pakistan has already made it clear that we are willing to go by the agreement that we had in the past," Foreign Minister Hina Rabbani Khar told PTI in an interview.

She said the two countries must move forward in the relationship and "moving forward would require that we all are able to sometimes show flexibility some times we don't need to show flexibility."

Khar is in the Cambodian capital to attend the ASEAN Ministerial meeting.

When asked whether Pakistan was disappointed that Indian Prime Minister Manmohan Singh has not yet decided to visit Pakistan despite invitation, Khar said "I do not believe in the business of being disappointed. I believe in optimism and I believe that we still would like to host him.

"We welcome him to Pakistan and we hope that within his tenure (he is able to visit Pakistan)."

"As I said, for me I look at it as a lost opportunity because there were two prime ministers who got along awfully well, who were able to set the course of a different dimension within this relationship,"

"So one of them is a former Prime Minister now. So we hope that more opportunities will not be lost." she said.
