The mainland has agreed to be more transparent about laws and regulations governing investment and trade under Cepa. In return, Hong Kong will give more information on its policies and regulations to mainland businessmen to give them a better idea about the city, director-general of Trade and Industry Kevin Ho Chi-ming said. Hong Kong and the mainland have agreed to co-operate further on customs clearance, e-commerce, quarantine and inspection, food safety and quality assurance. The two sides agreed that more co-operation was needed between small and medium-sized enterprises on both sides of the border and that the two governments would promote trade and investment overseas. They will also work together on the development and research of Chinese medicine. They will organise briefings and seminars so the private sector on both sides will be more knowledgeable on economic and trade policies, Mr Ho said. 'Many businesses in Hong Kong complain that they are pretty ignorant on mainland laws. We also found many mainland businesses don't know our laws very well, so both governments decided to have more co-operation on this area,' he said. There will be an annual meeting to review co-operation between Customs officials and a liaison system to strengthen co-operation. The newly appointed Commissioner of Customs and Excise, Timothy Tong Hin-ming, said his department would work out how to enforce the requirements of Cepa, especially on the rules of origin for Hong Kong goods. On the development of e-commerce, both sides agreed to co-operate on the formulation of rules and standards to create a favourable environment. They will also work to develop e-government initiatives.
