Islamabad: In the wake of the US raid in Abbottabad that killed Osama bin Laden, China has advised the US to "respect Pakistan's sovereignty and solidarity.

China has "warned in unequivocal terms that any attack on Pakistan would be construed as an attack on China", a media report claimed on Thursday.

The warning was formally conveyed by the Chinese Foreign Minister at last week's China-US strategic dialogue and economic talks in Washington, according to diplomatic sources.

Chinese Premier Wen Jiabao informed his Pakistani counterpart Yousuf Raza Gilani about the matters taken up with the US during their formal talks at the Great Hall of the People on Wednesday.

The report said China "warned in unequivocal terms that any attack on Pakistan would be construed as an attack on China".

The two premiers held a 45-minute one-to-one meeting before beginning talks with their delegations.

The Chinese leadership was "extremely forthcoming in assuring its unprecedented support to Pakistan for its national cause and security" and discussed all subjects of mutual interest with Gilani, the report said.

Gilani described Pakistan-China relations and friendship as "unique".

Talking to Pakistani journalists accompanying him, he said that China had acknowledged his country's contribution and sacrifices in the war against terrorism and supported its cause at the international level.

"China supported Pakistan's cause on its own accord," Gilani said with reference to the Sino-US strategic dialogue where the Chinese told the US that Pakistan should be helped and its national honour respected.

Gilani said China has asked the US to improve its relations with Pakistan, keeping in view the present scenario.

Pakistan reiterated its position on the one-China policy and said it fully supports China on the issues of Taiwan and Tibet, he said.

He said both sides will continue their consultations on UN reforms.

It was also agreed that both countries will formulate a long-term joint energy mechanism for electricity generation in Pakistan through various means, including nuclear energy.

Wen announced that the Chinese leadership will send a special envoy to Islamabad to express solidarity with Pakistan at this "crucial period in its history".

The envoy, a senior minister, will take part in celebrations marking the 60th anniversary of diplomatic ties between the two countries. The US has stepped up pressure on Pakistan to crack down on terrorist sanctuaries and to probe whether military and intelligence officials were aware that bin Laden had been hiding in the garrison city of Abbottabad, which is home to thousands of soldiers.

Pakistan has turned to China, its "all weather friend", for support in the face of reports that US lawmakers are pressing for cuts in aid.

China has agreed to provide Pakistan 50 new JF-17 Thunder multi-role jets under a co-production agreement, according to reports.

It is likely that these planes will be supplied by June next year.

The two countries are also discussing the supply of Chinese J-20 stealth jets and Xiaolong/FC-1 multi-purpose light fighter aircraft to Pakistan.

They are discussing the mode of payment and the number of planes to be provided to Pakistan, the report said.

China will also launch a satellite for Pakistan on August 14.

The satellite will supply "multifarious data" to Pakistan, the report said.
