BEIJING - The four newly-appointed top officers of the Chinese armed forces chorused loyalty to the ruling Communist Party of China (CPC) and military modernization at their debut to the ongoing CPC national congress in Beijing.

Fang Fenghui, chief of the General Staff Headquarters of the People's Liberation Army (PLA), Zhang Yang, director of the General Political Department, Zhao Keshi, head of the General Logistics Department, and Zhang Youxia, head of the General Armament Department, all eulogized Hu Jintao's address to delegates to the 18th CPC National Congress, which is held from Nov 8 to 14.
