China has maintained the drive to expand and modernize its armed forces despite high levels of government debt and a slowing economy, partly as a result of the coronavirus pandemic.
Beijing has said China's military budget — the second-largest in the world after the United States — is set to increase by 7.1 percent in 2022.
Some 1.45 trillion yuan ($230 billion) has been set aside for national defence, according to a government budget report on Saturday.
The increase is slightly higher than the 6.8 percent rise last year and broadly in line with the general pace of growth in recent years.
It exceeds Beijing's annual GDP growth target of 5.5 percent announced separately by Premier Li Keqiang on Saturday.
During a speech opening the annual session of China's rubber-stamp parliament, Li said Beijing would "enhance military training and combat readiness, stay firm and flexible in carrying out military struggle, and safeguard China's sovereignty, security and development interests.”
Beijing has poured billions of dollars into defence modernisation in recent years as it aims to transform its huge military into a world-class force rivalling that of the United States and other Western powers.
Military tensions have dramatically increased over the past year between China and rivals including the US and India as Beijing has overseen an island-building spree in the South China Sea, clashes on the Himalayan border and sabre-rattles over Taiwan.
Li made no reference to those tensions other than a standard warning against any "separatist activities" in Taiwan and "foreign interference" in the self-ruled island's status.
Beijing's military budget is still far lower than Washington's, which has over $700 billion earmarked for defense spending for 2022.
But many overseas military analysts believe actual spending is significantly higher than the publicly announced budget.
"The People's Liberation Army (PLA) is the armed wing of the Chinese Communist Party and the party leadership needs to secure the continued support from the military leadership," said James Char, an expert on the Chinese military at Singapore's Nanyang Technological University.
"One of the ways to do this is by demonstrating that the needs of the PLA are being prioritised."
Chinese President Xi Jinping last month called on the military to conduct "combat-oriented tests" and increase the capacity for "intelligent, information-based warfare."
Over the past year, China has conducted two flight tests of hypersonic ballistic missiles.
