The NATO summit gathering heads of member states and governments started Monday in Brussels.

The leaders will discuss a wide range of issues, including the main themes of the NATO 2030 initiative: how to reinforce the alliance’s unity, broaden its approach to security, and contribute to safeguarding the rules-based international order.

Also, decisions to prepare NATO for the challenges of today and tomorrow, including “Russia’s pattern of aggressive behavior, terrorism, cyber-attacks and disruptive technologies, the rise of China, and the security implications of climate change”, will be taken.

Transatlantic relations are also among the topics as the US will attend the summit under the new Biden administration.

Since Sunday evening, the leaders were holding bilateral meetings on the sidelines of the summit and those meetings will continue to be held until the end of the summit.
