Because it supported the Russian invasion of Ukraine
On Tuesday, Britain said it would impose new economic and trade sanctions on Belarus, including the country's transport sector, over its support for Russia's invasion of Ukraine.
The new package will include a ban on importing and exporting goods worth around £60m, including exports of petroleum products, high-tech components, luxury goods, and imports of Belarusian iron and steel.
Britain will also ban more Belarusian companies from issuing debt and securities in London.
Belarussian pro-Kremlin foreign policy has brought many western sanctions on Minsk. In 2021, Belarus allowed many refugees to use its territory as a transit to the European Union. European Union countries such as Poland fenced their borders to prevent anyone from entering their country, and it moved them to introduce sanctions against Minsk.
