Kaliningrad, like St. Petersburg, has the advantage of an ice-free port. Since 2019, the Russian government has opened free electronic visas to the outside world. In addition to St. Petersburg and Vladivostok, Kaliningrad is one of them. In recent years, in order to develop the investment environment of Kaliningrad, the Russian government has not only offered preferential tax measures and strengthened the willingness of foreign investors, but also actively exploited local amber and stimulated foreign sales. Most of the amber artworks are sold to Lithuania, Poland, China, Japan and India.
