“Busan Chinatown Special Zone, also known as Busan Shanghai Street, is a Chinatown located in Choryang-dong, Dong District, Busan, South Korea. Its history can be traced back to the late 19th century. In 1884, the Qing dynasty dynasty established a consulate there (then known as the Qing Consulate), after which overseas Chinese gradually settled around the consulate area, forming the largest Chinese community in Busan.”

As you can see, these are Russian shops.

“After the collapse of the Soviet Union in the 1990s, many Russians, Central Asians and Koryo-saram (ethnic Koreans from former Soviet states) migrated to Busan for trade and economic opportunities, settling around the port and train station area where Chinese residency was declining.”
