"Due to restrictions imposed on exports to Russia by the United States, United Kingdom, and the European Union, leading Taiwanese companies were among the first to cease working with Russia after the country started full-scale war against Ukraine in late February. This week Taiwan's Ministry of Economic Affairs (MOEA) formally published its list of high-tech products that are banned from exportation to Russia and Belarus, which prevents all kinds of Taiwan-produced high-tech devices as well as tools used to make chips (whether or not they use technologies originated from the U.S., U.K., or E.U., which were already covered by restrictions) to be exported to the aggressive nation.  " "Items banned from exportation to Russia and Belarus are pursuant to Category 3 to Category 9 of Wassenaar Arrangement, which covers electronics, computers, telecommunications, sensors, lasers, navigation equipment, maritime technology, navigation, avionics, jet engines, and a number of other categories.  "
