China sought to reassure foreign corporate chiefs of the country’s business potential when Vice Premier He Lifeng met with the heads of Apple, Pfizer, Mastercard, Cargill and others on Sunday.

Beijing is keen to woo foreign investment amid heightened geopolitical tensions, as policymakers try to boost domestic consumption in a slowing economy to offset the impact of US tariffs.

American direct-selling firm Amway was monitoring the impact of US tariffs, but its chief executive, Michael Nelson, said the company is focused on the future of the Chinese market, according to Global Times.
