In case you haven't been paying attention China has been rapidly modernizing its armed forces and expanding them too (including making artificial islands in the South China Sea and arming them). The Russians have developed the new T-14 Armata main battle tank to rival or best the Abrams M1A2, the new PAK-FA (T-50) fighter jet to rival or best the F-22, the new S-500 missile system, new Borey class ballistic submarines, new modern hypersonic missiles, and modernizing their battle cruisers and destroyers.
