When China conducted lunar probe research and feasibility study, there were few moon probe activities in the world and most countries had not announced any new lunar exploration plans. "Our decision-making process was carried out without any exterior influences," Luan said.

Chinese space experts, technicians and other work staff, joined by experts from Japan, Germany and other countries were watching the launching process on the spot Wednesday.

More than a month ago, Chinese space experts were also invited to the launch site of a Japanese lunar satellite.

"China welcomes international cooperation in space activities," said Vice Minister of Science and Technology Li Xueyong, adding China hopes to become the 17th nation to join the International Space Station (ISS) project.

The International Space Station is a joint project of 16 nations including the United States, Russia, Japan, Canada, Brazil and 11 countries from the European Space Agency.

"China sincerely wants to cooperate with the United States in space exploration and join the International Space Station project that has already involved 16 nations," said Li.
