 And Boris Johnson has welcomed Joe Biden's new pledge to double U.S. financial aid. The aid to help developing nations tackle the climate crisis as he arrived in Washington, D.C., for talks with the U.S. president. The prime minister said Washington's massive contribution of $11.4 billion annually by 2024 was a very, very good start. His target is securing $100 billion from world leaders, but there's still a long way to go. Very good news in the sense that the United States has stepped up to the plate with a massive contribution, a very substantial contribution, $11.2 billion, I think it is. And that's a very, very good start. It means that we're a long way towards the goal that we need to achieve. There are still countries around the world that will be looking to us in the developed world to support them as they make the transition to low-carbon technologies to fight climate change. But there's no question that this American action today has been a big lift and will really help us to get that.
