The US has tightened its rules on exports to Russia
The US government has tightened export restrictions of Russia, China and Venezuela. The relevant document, the Bureau of industry and security of the Ministry of industry and trade was published in April, and on 29 June came into force.
The new rules relate to the issuance of licenses for the export to specified countries of goods that can be used by military or for military purposes. This list includes dozens of new positions in the field of instrument and engineering, telecommunications, software and technology, including space (excluding required for operation of the ISS), sensors, lasers, and other similar equipment. For the export of such equipment requires special permission of the us authorities.
As justification for this decision, the Bureau calls the national security Strategy of the United States, which stipulates that Russia and China "support the dictatorship in Venezuela and seek to expand military ties and arms sales throughout the region."
In Venezuela at the beginning of 2019 began mass protests against President Nicolas Maduro shortly after the oath of office. The head of the National Assembly Juan Guido illegally declared himself interim head of state. A number of Western countries led by the US announced its recognition of Guido. In turn, Maduro called the head of the Parliament a puppet of the US. Russia, China, Turkey and several other countries have supported Maduro as the legitimate President.
