What happened? 
On 13 June, during his visit to Europe to take part in the G7 and NATO summits, the US President declared, "America is back at the table." 

On 16 June, in Geneva, Biden remarked: "They're glad America is back, and they acted that way. And then, when we went to NATO, I think it was the same thing. We had really good meetings there and real response, as well as the EU. I didn't get one single person — not one of the world leaders said to us anything other than thanking me for arranging a meeting with Putin. And I thought, quite frankly, I was in a much better position to represent the West, after the previous three meetings with Putin, that — knowing that the rest of the West was behind us."

What is the background?
First, Biden's approach towards Europe vis-à-vis Trump's. Biden has promised to bring an end to the pandemic and address climate change, which Trump did not. During his visits, Biden emphasized joint cooperation in security and defence, against Trump's idea of making America great again by withdrawing. Through his engagements with Europe in various areas of trade and technology, he is proving that Europe is back at the stage of global diplomacy. He has also managed to address the three important issues: China, COVID and climate change. 

Second, Biden's coalition on China. The US, along with the G7 countries is planning to counter China's BRI project with the idea of 'build back better world' and global infrastructure partnership. During his visit to Europe, Biden got the consensus of G7 also on addressing China' military assertiveness.

Third, improving the lines of communication between Russia and US. A constructive consultation on cybersecurity and the return of the ambassadors to their diplomatic posts were a positive outcome. Both Biden and Putin have agreed to replace the START treaty. 

What does it mean?
Through the G7 and NATO summits, Biden has built a consensus of the West on Russia and China. With Russia, his meeting with Putin should be seen as a breakthrough to prevent the downward spiralling of the US-Russia bilateral relations. While Biden's Europe tour has consolidated the trans-Atlantic partnership, it has also addressed the recent negativity in the bilateral relations with Russia.
