Sweden-Korea Polar Connect Roundtable Dialogfrom Per Nihlen (CTO at SUNET/Swedish Research Council)'s linkedin Posts A truly fantastic week in Seoul 🇰🇷🇸🇪🇪🇺We had the privilege of holding a roundtable discussion on Polar Connect in Seoul. A strategic dialogue on how a direct digital link between Europe and Korea could serve as a cornerstone for future connectivity. Such an infrastructure would not only enhance resilience, reduce latency, and secure greater capacity, but also play a key role in bringing our digital economies closer together.By enabling faster, more secure, and sustainable data flows, Polar Connect has the potential to strengthen innovation ecosystems, digital trade and research collaboration, while also providing critical infrastructure for the development and deployment of AI and data-driven technologies.This initiative represents an opportunity to continue building on long-term trust, reinforcing partnerships, and establish new frameworks for cooperation. Ensuring that Sweden, Europe and South Korea remain at the forefront of the global digital transformation.A special thanks to His Excellency Ambassador Karl-Olof Andersson for generously hosting us at the Swedish Residence, and to Director General Katarina Bjelke, Director General David Edvardsson, Director Buseung Cho and Dr. Rainer Wessely for their insightful presentations, strong commitment, and leadership in moving this important agenda forward.hashtag#PolarConnect hashtag#Vetenskapsrådet hashtag#NORDUnet hashtag#Polar hashtag#Sweden hashtag#SouthKorea hashtag#EU hashtag#Kisti hashtag#CEFDigital hashtag#DigitalEU
