 U.S. President Joe Biden has called on other world leaders to take action to reduce supply chain problems and prevent them from happening in the future. He was speaking to fellow leaders who gathered for the G20 summit in Rome. Supply chains are something that most of our citizens never think twice about until something goes wrong. And during this pandemic, we've seen delays in backlogs of goods from automobiles to electronics, from shoes to furniture. And in the pandemic is the ultimate key to unlocking the disruptions we're all contending with. But we have to take action now, together with our partners in the private sector, to reduce the backlogs that we're facing. And then we have to prevent this from happening again in the future. Now that we have seen how vulnerable these lines of global commerce can be, we cannot go back to business as usual.
