US President Joe Biden's opening remarks at the second in-person Quad summit in Japan's Tokyo laid emphasis on the Russia-Ukraine war and the world's response to the same. "We are navigating a dark hour in our shared history - Russia's war on Ukraine. It is a humanitarian catastrophe that is more than just a European issue, it's a global issue. [Russian President] Putin is trying to obliterate Ukrainian culture. He's not just hitting military targets - they are targeting every school, every church. The world has to deal with this," he said. Speaking on the Quad leaders' role, he said, "The US will be a strong, steady and enduring partner in the Indo-Pacific. We are Indo-Pacific powers<strong>. </strong>As long as Russia continues the war, we are going to be partners and lead a global response." The Quadrilateral Security Dialogue, colloquially the Quad, is a strategic security dialogue between India, Australia, Japan, and the United States. <h3><b>'LOTS OF WORK AHEAD OF US'</b></h3> US President Joe Biden said on Tuesday that the Quad partnership had already accomplished a great deal, especially with regard to Covid response and technology supply chains, but still had a lot of work ahead of it. He said, "Quad partnership is central to achieving our goals. We stay together for the shared values and vision we have. The Quad has a lot of work ahead of us to keep this region peaceful and stable and address the climate crisis." <div class="story-recommended-chunk"> <div id="readmore" class="readmore"> <div class="readmore-head"> He concluded, "Quad means business - I am proud of what we're building together." </div> </div> </div>
