Russia has not proposed Su-35 to China..
Because Russia know China won't buy SU-35 even proposed;
Here are the reasons;
Could the Chinese J-11s be better than the Russian Su-35s?

It would be a great irony if the copy was better than the original. All indications are this could be true. The latest versions of the J-11 will be steathier, equipeed with more powerful engines with more thrust, and have more avionics than the original Su-35 which have been in design for the past two decades.
Several years ago, China signed a contract authorizing it to assemble 200 Su-27SK fighters. After building 105 planes, China unilaterally suspended the deal. Many believe that China is manufacturing a fighter that is in effect a replica of the Russian Sukhoi SU-27. Russian arms “Made in China”. China used the opportunity to develop its own domestic manufacturing and now has local capacity to build the next generation of aircraft. Why did Pakistan buy fewer F-16s? Hint:-Indigenous Flanker!
Russia has supplied China with weapons worth a total of more than $25 billion for the past 15 years. Aircraft, ships and air defenses account for the bulk of this sum.
The Su 35s are in trouble. The prototype crashed, and it is not as stealthy as the F-22 its closest rival
One of the two prototypes of the Russian Su-35 fifth generation fighter crashed on takeoff on April 26th. The cause was a problem with one of the two engines. A third prototype is already under construction. Russia had hoped to have the destroyed prototype fly over the May Day parade in Moscow on May 1st. The crash is really bad PR, since one of the consistent shortcomings of Russian warplanes has been the unreliable engines.
Last July, this long promised Russian answer to the F-22, the Su-35, had its first flight. In late 2007, the Russian Air Force showed off the first of two flyable prototypes. It was three years ago, that Russia announced its long promised Su-35 fighter, was back in development again.
The Su-35 is an enhanced Su-30 (itself a development of the Cold War era Su-27), and has been in development since the 1990s. At one point, it was called the Su-37, but the name was changed back to Su-35. Since the 1990s, time, many Su-35 prototypes were built, and apparently no two were identical. There were many disagreements over what direction the development should take, and by the late 1990s, the project was basically suspended for lack of funding. Stratfor.

China’s armed forces have more than 280 Su-27SK, Su-27UBK, Su-30MKK and Su-30MK2 fighters.
