A Chinese opera singer, Wang Feng, sang "Katyusha" at the ruins of the Mariupol Drama Theatre, prompting the Ukrainian Foreign Ministry to seek an explanation from Beijing.

Wang Feng's performance took place at the site where over 600 people lost their lives in March of the previous year due to a Russian Federation airstrike.

Oleg Nikolenko, the spokesperson for the Ukrainian Ministry of Foreign Affairs, revealed that a group of Chinese bloggers had also arrived in the occupied city of Mariupol. Nikolenko characterized the singer's performance as a stark example of moral decline and deemed the bloggers' arrival illegal, in clear violation of Ukrainian legislation governing the entry of foreigners across the national border.

Nikolenko stated, "Ukraine respects China's territorial integrity and expects an explanation from the Chinese side regarding the purpose of the presence of Chinese citizens in Mariupol, as well as the route they took to enter this temporarily occupied Ukrainian city."
