China is aggressive and very intelligent with their goals and roadmaps in complete contrast to other emerging mega-nations like India, and sadly even in contrast to Europe which seem to have both the financial and the human capital to become a world leader however lacks the the will and the uniform vision to achieve that.
Don't get me wrong Europe is doing some amazing things in research especially in the academic scene and programs like Horizon 2020 are pretty impressive but they are peanuts in the grand scheme of things, China on the other hand says in 10 years I want to be able to make X and they get there doesn't matter if X is canned goods or high end CPUs.
China is the US in the 50's be the 1st in everything, do huge national projects to get there, invest in science, technology and education all for the national pride and glory. As much as I'm "scared" of China I really admire their moonshot spirit in the past decades if they won't implode before getting there I hope they'll end up being benevolent overlords.
Or they could just invade Taiwan for its fabs.
All of them use various sub-wavelength techniques like using multiple stencils and masks to create aperture / fresnel lense like effects etc.
Pretty much since you have multiple measurements for "feature size" like fin, gate, interconnect pitch etc. companies are just naming their process roadmap to show "progress". I don't think even Intel's 14nm process actually has a 14nm "feature size" and if it does I don't know what measurement they are basing it on.
