President Donald Trump recently renewed calls for a territorial land swap between Russia and Ukraine a geopolitical maneuver that, if pursued, could grant Moscow control over some of Ukraines most strategic and resource-rich regions.Ukrainian President Volodymyr Zelenskyy has firmly rejected any proposal that would allow Russia to retain control of its occupied territory in the war-weary country.ZELENSKYY WONT CEDE TERRITORY FOR PEACE DEAL AHEAD OF TRUMPPUTIN SUMMITRussia currently occupies approximately one-fifth of Ukraines territory, primarily in the eastern and southeastern regions, including large swaths of Luhansk, Donetsk, Zaporizhzhia and Kherson.These areas have been under partial or full Russian control at various points over the course of the Kremlins three-and-a-half-year war.Russia also holds Crimea, Ukraine's southern peninsula, which it annexed in 2014. The seizure of Crimea triggered a wave of international sanctions and led to Russias expulsion from the Group of Eight."The land that Russia currently occupies in Ukraines south and east is rich in various natural resources," said David Salvo, the managing director of the Alliance for Securing Democracy at German Marshall Fund."Should Russia keep that land, theyd be stealing vast quantities of critical minerals and other key economic assets. This includes important commodities on the global market, like lithium, coal, and gas," added Salvo, who previously served as the deputy secretary of states policy advisor for Europe, Eurasia and international security issues.This strategic importance is underscored by a warning from the Institute for the Study of War, a non-partisan, nonprofit research organization based in Washington, D.C., which cautions that Russia could exploit rare-earth mineral deposits in occupied Ukraine and sell them to China.ZELENSKYY THANKS NATO, EUROPEAN LEADERS FOR BACKING HIS PUSH TO JOIN TRUMPPUTIN SUMMIT"Russias access to minerals in occupied Ukraine will likely augment the People's Republic of China's ability to access Ukraines minerals," the Institute for the Study of War wrote in a statement to Fox News Digital, adding that Russia has previously worked with China to extract these commodities around the globe since at least 2005."The U.S.Ukraine mineral deal signed in April 2025 will only be effective if U.S. and Ukrainian companies can access those resources," the statement from the Institute for the Study of War went on to say, noting the challenge given that Russian forces currently hold territory containing significant deposits.Salvo said that Russia's occupation of Ukrainian territory along the Black Sea not only restricts Ukraines sea-based exports, but also grants Moscow control over valuable offshore gas reserves.Salvo also estimates that Ukraine, historically known as Europe's breadbasket, stands to lose billions of dollars in grain export value."Ukraines economy would survive, but it would undoubtedly lose in the hundreds of billions," Salvo said.Before Russia's full-scale invasion, agriculture was Ukraines third-largest economic sector, contributing nearly 11% of GDP and employing about 2.5 million people, according to a 2024 European Parliament report.According to the latest review from the Kyiv School of Economics, the Ukrainian agriculture industry has sustained approximately $80 billion in damages and losses.The group also projects that the countrys economy will shrink by 45%, while disrupted grain exports and ongoing destruction of its agricultural sector threaten millions worldwide with hunger.
