Chief Executive John Lee arrived in Shanghai after attending the opening ceremony of the 29th Beijing Hong Kong Economic Cooperation Symposium in Beijing. On Wednesday afternoon, Lee mentioned in a Facebook post that he met representatives from the Ministry of Commerce, Beijing's Liaison Office in the SAR, and the Shanghai Municipal People's Government at the airport, and thanked them. On Thursday, Lee will participate in the opening ceremony of the ninth China International Import Expo (CIIE), which has attracted participants from 162 countries, regions, and international organizations, with a total exhibition area exceeding 440, 000 square meters. In addition, Lee will attend the Hongqiao International Economic Forum, where he plans to highlight Hong Kong's role in integrating into and serving China's development. Shanghai and Hong Kong share a long history of cooperation, and this year, Hong Kong aims to establish a "sister port" relationship with Shanghai. Lee also launched a pilot project for the mutual exchange of trade data, which is expected to benefit local small and medium-sized enterprises exporting goods from the mainland. He is expected to meet with Shanghai officials before returning to Hong Kong on Friday.
