The U.S.-R.O.K Summit, which was held shortly after the Yoon administration took office, confirmed the two countries’ commitment to an alliance in economic security and technology in areas like advanced technology and supply chain, developing a set of guidelines for their future cooperation. Meanwhile, tensions are growing in the R.O.K-China relations as Seoul has decided to join the IPEF(Indo-Pacific Economic Framework), often regarded as an anti-China coalition led by the U.S. What opportunities and challenges do techno-political factors derived from the U.S-China competition bring and pose for both South Korean government and businesses, given that analysts now believe that Seoul’s dual positioning of partnering with Washington on security and relying on China on economy has now come to an end? Is there any strategy that can bring development and survivability in the face of a clearly apparent global blocization for middle powers like South Korea? Is there really no driving force for the U.S.-China cooperation?
