"We have made efforts to invite buyers from countries and regions along the 'Belt and Road'," said Liu.

Citing increased trade over the years between China and the Association of Southeast Asian Nations, or ASEAN, which will be key trade partners along the ancient maritime silk route especially, Liu said the Belt and Road Initiative would provide huge opportunities for trade growth.

The number of buyers from ASEAN members expected at this year's spring session have increased 2.29 percent from the same time last year, with 90 percent of all firms that took part then returning this year.

Liu said a total of 24,713 domestic and overseas companies will attend the fair, almost equaling the last session's number.

"This number of participants shows companies still have a growing interest in shipping goods overseas," Liu told a news conference on Monday, adding companies promoting their own brands particularly are expected to see a rise in deals during the half-month trade event.

"Companies with self-owned brands received big orders during the previous sessions, and this upward trend will continue," said Liu.

Gree Electric Appliances Inc, one of the country's leading home appliance makers, which has been growing a strong international presence, will be exhibiting a number of its most recent innovations at the show.

Boosting its sales overseas would remain a priority, said a spokesman for the Guangdong-based company. In the first three months of the year, Gree has seen a strong growth in sales to Pakistan, for instance, where its share of the air conditioner market has increased to 28 percent.
