Four wars have already been fought on the Kashmir issue and the region still "was a flashpoint", but in the 21st century "we cannot afford wars", Gilani said.

"We want to resolve issues through dialogue, diplomacy, prudent policy and national consensus," he said while addressing a convention at the Prime Minister's Secretariat to mark 'Kashmir Solidarity Day'.

Gilani said the Kashmir issue remained the cornerstone of the country's foreign policy.

"We are committed to continue with the moral, political and diplomatic support to Kashmiris. The whole nation, including all the political parties, is united on the cause of Kashmir," he said.

Since Pakistan is a responsible country and a responsible nuclear power, it has to make responsible policies, Gilani said.

Pakistan's policies should be made through national consensus and by the chosen representatives of the people, and not by individuals, he said.

The Kashmir policy had been the focus of the Pakistan People's Party-led government in line with the vision of the party's founder, Zulfikar Ali Bhutto, he said.

Rallies were held across Pakistan to mark 'Kashmir Solidarity Day', which is a public holiday.

The day has been observed by Pakistan since 1990 to highlight the Kashmir issue.

During the rallies, Pakistanis pledged to continue supporting the Kashmiris for what they claimed was their "right to self-determination".

Special prayers were offered at mosques and hundreds of people formed a human chain in Pakistan-occupied Kashmir.

Banners calling for Kashmir's freedom were put up along roads in cities and towns across Pakistan.

Citing the policy of Pakistan-China friendship, Gilani told the convention at the PM's Secretariat that the whole country was united on this policy.

As in the case of Pakistan's policy on China, there was no difference of opinion on the Kashmir cause, he claimed.

Gilani noted that there were question marks about Pakistan's policy on Afghanistan as it was made by a dictator who wore the four hats of the Chairman of the Joint Chiefs of Staff Committee, the army chief, the President and the Chief Executive.

Despite his power, the dictator could not sustain pressure after a call from a US Under Secretary, he said.

In contrast, the democratic government closed NATO supply lines, got the US to vacate Shamsi airbase and boycotted the Bonn Conference on Afghanistan after NATO attack on Pakistani border posts in November last year, he said.

President Asif Ali Zardari, in a special message, reiterated Pakistan's "fullest moral, political and diplomatic support to Kashmiris".
