The stage is set for this year's World Economic Forum in Davos, themed "A Spirit of Dialogue," with global attention firmly on US President Donald Trump, who is set to address the forum this week. Trump's appearance comes amid rising tensions with Europe after he announced a 10 per cent tariff on exports from eight European nations, including Denmark, Germany and France, effective February 1. European leaders have criticised the move as damaging to transatlantic ties, while Trump has linked the decision to US security interests in Greenland and the Arctic.
