Russia sells military hardware to China, and recently delivered to Beijing a number of Su-27s, an earlier generation of fighters.
But China and Russia remain wary of one another and that appeared to be one of the reasons behind Moscow's decision.
"The delivery of Russian Su-35 fighters to China is now out of the question,'" Gennady Yanpolsky, deputy chairman of the State Committee for Defense Industries, told Itar-Tass.
He said Russia was "very careful" about selling weapons abroad and needed to review how such sales might affect Russian security.
Yanpolsky was responding to reports that China had allocated $5 billion in 1994 to purchase Russian military equipment, including the Su-35 fighter plane.
He said Russia was presently offering only the Su-27 and Su-30 models for sale.
The updated Su-35 is still being developed and is "mostly for demonstration purposes," Yanpolsky said.
Rosvoorouzhenie, the Russian state arms company, boasts that the Su-35 is superior to its main American rival, the F-15 fighter jet.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
