Digressing I know but I have heard that the Chinese Navy have a problem with their vaunted carriers. Russia has cancelled the order for 50 Su33 aircraft that China placed.
Russia has just twigged that China has a habit of producing cheaper versions of almost anything they buy, in this case the Su27 in direct violation of signed agreements. China bought 200 Su27's (J-11) and then produced their own version (J-11B), in itself not allowed in the original agreement and offered this for export in direct competition with the Russian version, which has really ticked the Russians off.
This leaves China with a problem as to where to get their carrier aircraft from. We can take it as read the USA isn't going to sell them any and the only other producer of carrier aircraft, is France.
