Invited by Li, Cameron arrived in Beijing on Monday morning for a three-day official visit to China.

Hong said China has consistently advocated the complete prohibition and destruction of all nuclear weapons while firmly pursuing a nuclear strategy solely for self-defence; has adhered to a policy of no first strike at any time in any circumstances; and made an unequivocal commitment not to use or threaten to use nuclear weapons against non-nuclear powers or nuclear-free zones.

When outlining China's diplomatic priorities for 2014 earlier this month, Wang said China would strive for an "early harvest" in those efforts.

China will consistently adhere to the principle of peaceful use, equality, mutual benefit and common development in the construction of its manned space station, due to be completed around 2020, Wang Zhaoyao, director of the country's manned space program office, told an international seminar in Beijing.

It is a common aspiration of both governments and peoples to strengthen their strategic partnership, which will play an important role in safeguarding regional peace, stability and development, and in promoting unity among developing countries, he said.
