The leaders of the Group of Seven (G7) industrialised nations meet in Cornwall, UK, this week for their first summit since the outbreak of COVID-19. They will focus on global challenges including the pandemic, climate change and threats to democracy, on top of economic concerns. After a period of friction among Western nations – largely due to the antics of former U.S. President Donald Trump, who was a disruptive presence in G7 meetings from 2017 to 2019 – leaders want to show a united front against China and Russia. U.S. President Joe Biden’s visit to Cornwall will be his first foreign travel since taking office, adding lustre to the occasion.
