Donald Trump's re-election sets stage for fresh global economic and geopolitical dynamics

The articles describe the ongoing activities of global leaders, including those attending the World Economic Forum in Davos, Switzerland. Donald Trump, the US President, has returned to the White House and has issued several executive orders, which include rolling back environmental regulations and withdrawing the US from the World Health Organization. The World Economic Forum, which will be attended by nearly 60 heads of state, 900 CEOs, and other high-ranking officials, is expected to be a significant event. Trump's video address is set to be a highlight, although it will conflict with the speeches of Ursula von der Leyen and Ding Xuexiang, the Chinese vice-premier, on Tuesday.
