The European Union (EU) and South Korea have agreed to work together on the development of 5G mobile broadband technologies.
A Joint Declaration on Strategic Cooperation will see the EU work with the south-east Asian nation to define the new standard.
The EU and South Korea will share research findings, in a bid to ensure global interoperability and consistency of approach.
Neelie Kroes, European Commissioner for Digital Agenda, claimed 5G will become "the new lifeblood" of the digital economy and society once it is established.
"Both Europe and Korea recognise this," she stated.
"This is the first time ever that public authorities have joined together in this way, with the support of private industry, to push forward the process of standardisation."
Ms Kroes said the declaration signals the "shared commitment" of the EU and South Korea to being global digital leaders.
