With stealth jets entering service, leaked pictures of new high-tech naval artillery and proud reports of maneuvers that "dare to shine the sword," China's armed forces are putting on a show of power as they lobby for greater defense spending.

Although it is the world's largest military, the People's Liberation Army has been privately unhappy that it got less than double-digit funding increases the past two years. It has recently been making the case that it needs more money to deal with increased global uncertainty, diplomats and several sources with ties to the armed forces say.

In the run-up to the defense budget's release at the annual meeting of China's parliament next week, state media outlets have been filled with coverage of military drills, advanced new equipment and thrilling tales of derring-do in a new film very loosely based on China's evacuating people from Yemen's civil war in 2015.
