Full coverage: Top Chinese legislator attends Belt and Road Summit

And for more on this, we speak to our reporter Zhu Dan in Hong Kong.

Q1. Hi, Zhu Dan.  As we've mentioned, this is the first visit by a central government leader since 2012. What more can you tell us about the purpose of the NPC Chairman's visit?  Why now?

Seeing, listening and speaking – with these three words, Zhang Dejiang who touched down in Hong Kong this morning summed up his agenda for his three-day visit to the city. He said he would listen to “all sectors of society” on “what recommendations and requirements they have” regarding the implementation of ‘one country, two systems’ and on the matter of Hongkongers running their city. He opened his remarks by conveying well wishes from President Xi Jinping to the people of Hong Kong. Zhang briefly recalled his life in Guangdong province when he fostered closer ties with Hong Kong. Later he visited the government headquarters, and listened to the report of HK's Chief Executive Leung Chunying and other government officials.He has praised the achivenment the HK government has made, and he is confident about the One Country Two Systems policy. He will attend the Belt and Road Summit, and he give a keynote speech in the Convention and exhibition Center tomorrow. He will also visit the Science Park in Tai Po and a public housing estate, as he wants to understand the development of Hong Kong’s innovation technology, youth ventures and retirement protection tomorrow.

Q2. Zhang Dejiang will also deliver a speech at The Belt and Road Summit on Wednesday.  What can we expect at the meeting?

As we all know the belt and Road initiative is a long-term plan designed to boost economic, trade,cultural and people-to-people ties between the China and more than 60 countries. The Initiative offers companies unparalleled opportunities to tap new markets along the Belt and Road countries. The question many people are asking now is what role can HK play in this initiative?

And that's why the NPC Chairman is here in HK for the Summit. He is expected to point out HK's important role as a fund raising center for the Belt and Road Initiative and the newly established Asian Infrastructure Investment Bank. Actually Hong Kong has always been a financial hub for China’s inbound and outbound investment. Last year, 68 percent of foreign direct investment in Chinese mainland – worth 126 billion USD –flowed through Hong Kong. Overseas investment by Chinese companies in 2014 stood at 123 billion US dollars, with 58 percent flowing through Hong Kong. And companies in HK have started to play their role in the Belt and Road Iniative, ealier I talked to the CEO of Bank of China HK limited, take a listen their plan. That's out interview with CEO of Bank of China HK limited. So given its strength in capital markets and its international connectivity, Hong Kong can finance the Belt and Road related projects through debt issuance and private equity in the city’s bond market.
