ISLAMABAD The Chief of Army Staff (COAS), General Ashfaq Parvez Kayani on Wednesday left for China on a five-day official visit. He is visiting China on the special invitation of Chinese People Liberation Army (PLA). During his visit, the COAS will meet senior military leadership of PLA and some government officials. He will discuss issues related to Pak-China defence cooperation and measures to further strengthen the bonds between the two Armed Forces as well as the nations. General Kayani will likely to discuss with Chinese authorities the issues related to Pak-US Strategic Dialogue, war on terror, regional security especially in the context of Afghanistan, US cooperation to help Pakistan in tackling energy problems and the US opposition to the proposed nuclear deal between China and Pakistan, according to US, that it requires a specific exemption from the Nuclear Suppliers Group (NSG). The US has served notice that it would object to the deal at a meeting of the 46-nation group that regulates nuclear trade and its rules forbidding sales of nuclear technology to such countries that have not signed the Nuclear Non-Proliferation Treaty (NPT). However, China has maintained that its agreement with Pakistan to supply two additional nuclear reactors was signed before its joining the NSG in 2004 and, therefore, it does not need its approval. Earlier, Chief of General Staff, Lieutenant General Khalid Shameem Wynne and other senior military officials and acting Chinese Ambassador saw the COAS off at Chaklala Airport.
