International Sponsors of War was a publicly available list of companies and individuals maintained by the Ukrainian National Agency on Corruption Prevention (NACP) in connection with the Russo-Ukrainian War, particularly the Russian invasion of Ukraine. It had no legal standing but was nonetheless impactful. By December 2023, the list included 46 companies from 17 countries and 261 individuals who, by doing business with Russia, contribute to Russian revenues and ultimately Russian military budget in their ongoing war with Ukraine. The list is contrasted with international boycott of Russia when by 2023 more than 1000 companies withdrew or divested themselves from Russia following the invasion of Ukraine. NACP viewed the list as a reputational instrument for elements of global supply chains, aimed at reducing Russia's financial and technological capability to damage Ukraine. In September 2022 the list was included into London Stock Exchange Group's database. Some companies among International Sponsors of War are also restricted in other countries.
