China's announcement of a 7% rise in military spending for the year came shortly after President Donald Trump called for a 10 percent increase in America's defence budget, prompting renewed scrutiny of how the two countries' capabilities compare, reports the Associated Press.
While the US military remains the dominant force in Asia and the world, China has been moving from quantity to quality and is catching up quickly in equipment, organisation and capability, and is increasingly able to project power far from its shores. Rapid economic growth, lavish spending and a desire to regain China's historical role as East Asia's leading power are helping drive the moves.
Below is a comparison of the present state of the two militarise, based on figures found in recent US government research on China's capabilities and information from defence think tanks and government websites. Some figures are estimates or approximations.
The big picture
China's People's Liberation Army has a total of 2.3 million personnel under arms, constituting the world's largest standing military. It provides only partial information about its order of battle, the PLA's mission and future plans, although outside analysts have produced detailed estimates. US troop strength varies depending on need, but as of January 31, there were 1.4 million active service members spread throughout the services.
Budgets
China announced last week that defence spending would rise by 7% this year to $151bn. While China has the world's second-largest defence budget, it's just a fraction of what the US spends, even if analysts' estimates of hidden additional spending are taken into account. Trump's request for an additional $54bn in spending would bring the US defence budget to a record $603bn, and that's before including tens of billions of dollars for overseas military operations. If approved, the increase would mean the US was spending 3.4% of its gross domestic product on defence, up from 3.2% of GDP last year. China says its budget this year would equal 1.3% of GDP.
Ground forces
Owing to the PLA's origins as a guerilla army and former tensions along its land border with Russia, the ground forces continue to dominate, with 1.6 million personnel and a weighty emphasis on armoured vehicles (9,150) and heavy artillery (6,246). The US army boasts 460,000 personnel with another 182,000 in the Marines. It has a smaller emphasis on artillery (1,299) and armoured vehicles (8,848), but places a greater emphasis on air support and special forces operations.
Air power
The US can boast more than 13,000 aircraft of all types to China's nearly 3,000. The gap is especially great in helicopters, where the US has more than 6,000 to China's 802. Despite having fewer aircraft, some of which are under the Chinese navy, China's air force has 398,000 personnel to 308,000 for the USAF. Both air forces are seeking to upgrade their aircraft, although the introduction of the fifth generation F-22 and F-35 jets puts the US several years ahead. China's stealth fighters remain in the prototype stage, although it has managed to replace more than half of its fighter fleet with fourth-generation aircraft.
Navy
China's navy has many more vessels (714 to 415), but the US has more where it counts in terms of power projection. The US has 10 aircraft carriers to China's one (although more are being built), 62 destroyers to China's 32, and 75 submarines to China's 68. The US Navy has 323,000 personnel to China's 235,000, reflecting the breadth and depth of a service that operates worldwide. China's navy has made strides in that direction since it established a permanent overseas presence by joining in multinational anti-piracy patrols off Somalia in 2008, and has begun exercising in the Western Pacific beyond the "first island chain" that blocks its access to open seas.
Missile command
The PLA has a completely separate branch, the Rocket Force, to operate its formidable arsenal of short-, medium- and long-range missiles, including those capable of delivering nuclear weapons. Estimates say China has a stockpile of approximately 260 nuclear warheads for delivery by nearly 150 land-based ballistic missiles, 48 sea-based ballistic missiles as well as bombers. The US has an estimated 1,740 nuclear warheads deployed for delivery by the same means. China's development of the DF-21D ballistic missile that is thought capable of threatening aircraft carriers has garnered much attention, although it remains untested in a conflict.
Overseas presence
China hasn't fought a conflict outside its borders since it invaded Vietnam in 1979 and officially eschews overseas alliances. Nonetheless, the PLA has been expanding abroad, from garrisons atop man-made islands in the South China Sea, to UN peacekeeping operations, joint naval exercises with Russia in the Mediterranean and the construction of its first overseas base in the Horn of Africa nation of Djibouti. The US military, in comparison, currently operates in more than 100 countries, maintains a worldwide network of alliances and is engaged in major conflicts in Afghanistan, Iraq and, increasingly, Syria.
