Chinese President Xi Jinping has announced a military restructure of the People's Liberation Army (PLA) to transform it into a leaner fighting force with improved joint operations capability, state media said.

Centred around a new, condensed structure of 84 military units, the reshuffle builds on Xi's years-long efforts to modernize the PLA with greater emphasis on new capabilities including cyberspace, electronic and information warfare.

As chair of the Central Military Commission, Xi is also commander-in-chief of China's armed forces.
