China's exports regained some momentum in June while imports rebounded, as firms rushed out shipments to capitalise on a fragile tariff truce between Beijing and Washington ahead of a looming August deadline, Reuters reported.

Businesses on both sides of the Pacific are waiting to see whether the world's two largest economies can agree on a more durable deal or if global supply chains will again be upended by the reimposition of duties exceeding 100%.

Customs data on Monday showed outbound shipments from China rose 5.8% year-on-year in June, beating a forecast 5.0% increase in a Reuters poll of economists and May's 4.8% growth, according to Reuters.

Imports rebounded 1.1%, following a 3.4% decline in May. Economists had predicted a 1.3% rise.
