A senior Chinese space official and military officer has been promoted to run the People's Liberation Army's key equipment development department, the military said on Monday, part of a reshuffle ahead of next month's Communist Party congress.

China's armed forces, the world's largest, are ramping up their capabilities with new equipment like aircraft carriers and stealth fighters, as the country pursues a more assertive stance in the disputed East and South China Seas and seeks to project power far from home shores.

In a brief story on its website about a military technology exhibition in Beijing, the Defence Ministry named Li Shangfu as the new head of the military's Equipment Development Department. It gave no other details of his appointment.
