Explanation:

The G4 nations comprise of Brazil, Germany, India, and Japan which support each other’s bids for permanent seats to United Nations Security Council.

G4's primary aim is the permanent member seats on the Security Council. Each of these four countries have figured among the elected non-permanent members of the council since the UN's establishment. Their economic and political influence has grown significantly in the last decades, reaching a scope comparable to the permanent members (P5). However, the G4's bids are often opposed by the Uniting for Consensus movement, and particularly their economic competitors or political rivals.
