About G7/G20 Youth Summits (Y7/Y20)

g7g20 youth japan
Y7 Summit and Y20 Summit (hereafter referred to as Y7 & Y20 Summits) are international conferences for youth leaders representing their own countries. As the official engagement group of G7 and G20 Summits, Y7 & Y20 Summits are held annually, hosted or supported by the host country of G7 and G20 Summit. Youth under 40 from a diverse background, such as researchers, government officials, and students, will convene ahead of G7 and G20 Summits and make policy recommendations by submitting the communique to G7 and G20. Y7 & Y20 Summits aim to propose solutions to various challenges faced by today’s international community by promoting mutual understanding among youth at the forefront of the world.
Y7 & Y20 Summits are regarded as a precious opportunity to reflect youth’s ideas to G7 and G20. Communiques adopted at Y7 & Y20 Summits are sometimes directly noted at G7 and G20 discussion, and youth delegates have the chance to meet top leaders from the host country.

Hosting Y7 Summit 2016

g7 g20 youth japan

We hosted Y7 Summit along with G7 Ise-Shima Summit. This was the first Y7 Summit to be hosted in Japan and also the first in the world to be hosted alongside the G7 Summit.

When Russia hosted G8 Summit in 2014, Y8 Summit was canceled due to the crisis in Crimea. When Germany hosted G7 Summit in 2015, Y7 Summit was also canceled since the significance of the event was questioned. There was a sense of crisis that G7/G8 would never come with a summit that allows youth engagement.

​Along with G7 Summit in 2019 hosted by Japan, we planned the “Y7 Summit.” We planned to invite five young professionals well-versed in G7 agendas from each of the G7 countries and the European Union to Japan, discuss international issues with over 400 general participants from Japan, and submit recommendations to be utilized in decision-making at G7. The Japanese government officials well understood this concept, and we successfully finished the summit with support from various entities and individuals.

​We would like to express our sincere gratitude to all those who supported our organization in hosting the summit.

IDEA Network

The IDEA (International Diplomatic Engagement Association) is made up of ascending leaders from around the world, from many different backgrounds and heading into a range of careers. G7 & G20 Youth Network, in 2006, our main focus was to organize the annual G7 / G20 Youth Summits, which brought together ascending leaders at the fringe of the G7_cc-781905 5cde-3194-bb3b-136bad5cf58d_and G20 summits. 

Since 2006, we have held these prestigious events in Russia, France, Germany, Japan, Canada, the United States, Mexico, the United Kingdom, Austrlia and Turkey. 136bad5cf58d_flagship events continue under the new name of the Y8 and Y20 Summits.

In 2012, we became The International Diplomatic Engagement Association (The IDEA), to reflect the growing desire of young leaders to build bridges beyond our major annual summits. to unite young leaders from around the world, and to facilitate their involvement in, and impact on, global issues through open dialogue and engaging diplomacy.

From Italy to Indonesia, South Africa to Saudi Arabia and the UK to the USA, our partners empower young people on every continent and recruit the best and brightest to represent their countries on the world stage. Seven years, we have trained and empowered over a thousand ascending leaders, who have all gone on to pursue leadership challenges at home and abroad.

Below is the list of our founding partners. If you are a member of a national youth organization that would like to become involved, get in touch.
