Washington, D.C., United States—The American government has imposed sanctions on the Chinese military over an order of Russian anti-air missiles and aircraft.

The sanctions came because of a twin Chinese purchase of 10 Russian Sukhoi Su-35 fighter jets in 2017 and batteries of S-400 surface-to-air missiles in early 2018. The State Department announced that the sanctions would specifically target China’s Equipment Development Department (EDD), the military agency responsible for weapons and equipment purchases, and its director, Li Shangfu.

US officials have said the sanctions are aimed at Russia and are not intended to undermine other countries’ defense capabilities, and similar action against other countries could be considered.

The Russian Foreign Minister Sergei Lavrov described the sanctions as economic warfare and “yet another act of unfair competition.”

The Russian Deputy Foreign Minister Sergei Ryabkov went on to say that by its actions America is undermining regional and global stability and thoughtlessly heating up the US-Russian relationship. “It would be not bad if they remembered about the concept of global stability which they are unthinkingly undermining by whipping up tensions in Russia-U.S. relations. Playing with fire is stupid and can become dangerous.”

Li is accused of transacting with Rosoboronexport, Russia’s chief weapons exporter. Li and the EDD are banned from transacting in the U.S. financial system (and its abundant capital) and applying for U.S. export licenses.

Rosoboronexport, alongside numerous other Russian agencies, companies, and individuals (including Russian President Vladimir Putin), has been sanctioned over the Russian interference in the 2016 US presidential election.  Interestingly, this was the 60th sanction package imposed on Russia.

“Each new round of sanctions proves our foe’s complete lack of success in pressuring Russia with previous such attempts,” added Ryabkov. Further, he stressed that despite U.S.’ sanctions, Russia will maintain an independent foreign policy.
