The United States added 71 Russian and Belarusian entities to its trade blacklist including several aircraft factories and shipbuilding and research institutes in its latest effort to deprive the Russian military of U.S. technology and other items, Reuters reports.

They include entities like several units of the Russian Academy of Sciences, and companies such as several aircraft plants and the Voronezh Joint Stock Aircraft Company, one of the largest Russian factories for passenger and cargo aircraft, according to several research reports. Also added was the Irkutsk Aviation Plant, which has manufactured nearly 7.000 aircraft of more than 20 types since 1934 and produces the MC-21 family of airliners.
