China has independently developed the “Long-March” rocket group, containing 14 types of launching vehicles capable of launching satellites into near-earth, geostationary and sun-synchronous orbits, launching manned spacecraft into space, and launching explorer into outer space. The overall technical performance of the rockets has reached the international advanced level and China has acquired a share of the international commercial launching market. To meet the demands of future development of space technology, China will accelarate its development of the new generation of launch vehicles with non-toxic, non-polluting, high-performance and low-cost qualities so as to increase China ´ s space-entering capacity，to promote the construction of national economy and to build up the comprehensive national strength.
