The partnership will help to raise the event's profile as the International Festival for Business (IFB) will advertise across CNN’s platforms.
Petra Malenicka, vice president, EMEA, ad sales at CNN International, said: "Advertising on our platforms will give the festival unrivalled visibility in front of key business decision makers and opinion leaders worldwide."
The IFB will host more than 100 events next year and forms a central part of the UK government’s goal of boosting economic growth, rebalancing the economy and doubling British exports by 2020.
Delegates will come from across the globe for a series of high profile events, exhibitions and celebrations, in order to realise the potential of global economic growth.
The IFB will focus on key areas of commerce that are transforming the business landscape of Britain and beyond, including manufacturing, science and technology; maritime, logistics and energy; knowledge, professional and financial services; higher and further education and research; low carbon and renewables; cities, enterprise and urban business; knowledge, creative and digital.
Leading figures from British business, alongside some of the UK’s most inspiring entrepreneurs, have pledged their support to the festival and become official ambassadors. The list includes former Tesco CEO Sir Terry Leahy; Terry Scuoler, chief executive, EEF and John Cridland CBE, director general of the Confederation of British Industry.
Max Steinberg CBE, chairman of IFB 2014, said: "For nearly three decades CNN International has provided compelling and in-depth coverage of breaking news around the world, broadcasting to audiences from all corners of the globe.
"The global business community regards CNN as a trusted news provider and commentator, with its finger on the pulse of the most important and pressing business issues. The festival is set to be the biggest global showcase of British industry in more than a generation."
Earlier this month, BT was announced as an official partner to the International Festival for Business.
