Re: Somali pirates and Chinese navy
Just because the Varyag might be completed in a few years does not mean she will be ready for combat operations and long distance tours then as well. It will be several years before the crew is trained up and enough tactics have been developed to be able to call her operational.
Even then the Varyag will most likely be limited in its operational duties as the PLAN will want to use her first as a test and evaluation ship, and then as a training carrier when they start building the domestic carriers so that there are trained up crews ready to take them out to sea as soon as they are built.
The Varyag is just a stop gap, a tool. The Chinese are too proud to make an ex-soviet carrier the crown jewel of their navy. The PLAN's real crown jewels will be the Chinese indigenous carriers and the PLAN's master timetable is set around them, and at current indications, that is planned for full fruition around 2020.
And the type 054 is just the light escorts. The PLAN is still undecided on the final DDG and SSN configuration, which should give you an indication of how far away operational Chinese carrier battle groups are right now. Sure they could cobble together an operational battlegroup with the Varyag when that is finished and its current inventory of warships, but that is far from the PLAN's current long-term objective, which is to have carrier battlegroups that can rival any other in the world. Maybe not quantitatively, but definitely qualitatively in terms of the carriers and the escorts.
There's plenty of time to build enough hulls for the PLAN's needs, and there is no indication that anything will change drastically enough to warrant the PLAN having to completely re-evaluation is maritime security outlook that would make a combat ready blue water navy an immediate requirement.
Sure a modern blue water navy is key to any power with more then regional interests and ambitions, but China has time to build one up at a leisurely pace that will not be difficult to sustain economically or cause undue alarm amongst the neighbors.
