The United States has the third-largest delegation of companies, said the Ministry of Commerce on Saturday.

Over 180 companies from United States have registered for the CIIE including Johnson& Johnson, DuPont, Qualcomm and Microsoft, led by their global chief executive officers, as the opportunity to participate in the CIIE appeals to the US companies, said Wang Bingnan, vice-minister of commerce at a press briefing in Shanghai two days before the event kicks off.

Wang said he hopes the companies from China and the US can work together, make full use of the platform of CIIE and achieve a win-win outcome.

US President Donald Trump said he supports American companies' participation in the first China International Import Expo during a phone call with President Xi Jinping on Nov 2.
