The Three Seas Initiative Summit hosted by Romania was organized on 17-18 September 2018 and aimed at marking important progress in linking the high level political investment of Heads of States to concrete deliverables. Therefore, the Summit aimed at achieving concrete progress in multiplying transport, energy and digital interconnections. Hungary was represented by H.E. Ambassador Botond Zákonyi.

One of the main objectives of the Summit was shortlisting major strategic projects in the three fields - energy, digital and transportation - thus answering the needs and priorities of participating states, while substantially contributing to the overall goal of the Three Seas Initiative.

The Summit aimed to attract the interest, support and participation of other important partners such as the EU institutions, international and regional financial institutions, business entities, relevant EU member states and to maintain the support of the USA in a transatlantic-unity approach and further explore potential synergies with other stakeholders outside the region.
