BEIJING - President Xi Jinping on Sunday ordered that China have a "military theory that is up-to-date, pioneering and unique" to support its strong and dynamic armed forces.

Greater efforts must be made to promote the innovation of Marxist military theory, Xi, also chairman of the Central Military Commission, told a military delegation to the National People's Congress at the ongoing annual session.

"A sound military theory is a key part of combat effectiveness. A strong army must have a sound theory as its guide," Xi said.

He urged military academics to link theoretical research with military practice.
