He said this during his speech at the Alexander Hamilton Society in Washington.
According to him, China "is still buying" Russian advanced weapons systems.
“Although I am absolutely sure that China does the same with Russian products, which it does in relation to many American products: they steal intellectual property, copy (produce), repeat”, RIA Novosti quotes him.
He also suggested that “very soon” China will start selling “the same weapons systems, but at a lower price than Russia.”
Earlier, Bolton spoke about the Chinese missiles threatening the "heart of Russia".
