The world’s two biggest economies agreed to a 90-day pause on most of their levies after a first round of trade talks in Switzerland over the weekend.

US President Donald Trump said China had agreed to remove non-tariff barriers to US imports as he announced a deescalation of his trade war with Beijing, suggesting even greater concessions could be in store if talks progress.
