Not a complete list, but some specifics to watch out for.
Nuclear Subs --- HTGR reactors with pump jet propulsion to create fast ultra quiet nuclear subs. Currently the state of the art in propulsion is held by the UK's Trafalgar and Astute class of subs, as well as the Sea Wolf. The PLAN should study the Astute class as a model for future nuclear subs.
Diesel subs --- Fuel cell propulsion. The PLAN should study the U-212 and 214s as the model for its next diesel subs.
Surface ships --- COGAS (Combined Gas Turbine with Steam propulsion). This is also known as recyclable gas turbines. Look to the UK's Type 45 warship. Also fuel cell hybrid propulsion.
Aircraft --- AESA in all fields. Sensor fusion.
National/Strategic --- Development of synthetic fuel and fuel cell technology. Nuclear energy, using small and safe reactors. China should get out of the petroleum habit.
