本届高峰论坛主题是：共建“一带一路”、开创美好未来（Belt and Road Cooperation, Shaping a Brighter Shared Future）。
37个国家的元首、政府首脑等领导人（leaders including heads of state and government from 37 countries）将出席论坛圆桌峰会（roundtable summit）。
The BRI has created a new dimension for the development of the world economy, and its long-term strategic plan is unusual, said President Ueli Maurer of the Swiss Confederation.
The Swiss president believed that globalization is the key to successful global development, and to achieve globalization, infrastructure construction at various levels would be indispensable.
In this sense, he said, the BRI is a future-oriented project that will contribute to globalization, in which everyone can benefit from improving and upgrading infrastructure.
For his part, Malaysian Prime Minister Mahathir Mohamad said he had advocated the revival of the ancient Silk Road for a long time and believed the BRI will boost connectivity between China and Southeast Asia.
"In the promotion of relations between countries, the distance as well as the speed of travel is very important. With this scheme, I am quite sure more ships will be passing near Malaysia and Southeast Asian countries and therefore it will increase trade between Southeast Asia and China."
Tajik President Emomali Rahmon called the Belt and Road a multi-faceted "bridge" which can help unlock the transit potential of the landlocked Central Asian country and enable it to access worldwide markets.
"The BRI implies creating a new model of international cooperation by strengthening the existing mechanisms, as well as seeking and implementing new mechanisms, with the aim of stimulating the economic development of countries involved," Rahmon said.
Calling the BRI a "fantastic infrastructure project," Czech President Milos Zeman said, "I encourage Czech companies to participate in the construction of the new Silk Road, especially the railway construction."
"My intention is to propose the Czech Republic as one of the possible countries for the communication with European countries. And the Czech Republic will not be omitted in the process," Zeman said.
Italy has become the first Group of Seven member to join the BRI, said Italian Prime Minister Giuseppe Conte.
Conte said Italy is glad to seize the historic opportunity to join the BRI, adding that he strongly believes that it will help fully explore the potential of Italy-China cooperation.
United Nations (UN) Secretary-General Antonio Guterres, who will host a seminar about green growth at the Belt and Road forum, said the BRI is a "very important opportunity" for the world.
With such a huge volume of investment for international cooperation brought about by the BRI, it is a "very important opportunity for enhancing the capacity to implement the sustainable development goals and an important opportunity to launch green perspectives in the years to come," Guterres said.
