 Good morning, good afternoon, good evening, ladies and gentlemen, distinguished guests. We are proud to take part in the Sixth World Policy Telecommunication Forum, a forum that forces achievement in our nation's sustainable development goals and leads the way for fruitful collaboration to develop policies that provide expedited digital, safe and affordable technology to everyone. Huawei's mission is to bring digital to every person, home and organization for fully digital connected and in time to work. We see this WTPF 21st as a great opportunity to contribute and get involved in the process of developing relevant telecommunications industry policies, leveraging the United Nations Specialized Agency for Information and Communication Technologies, the ITU as a global convening platform for this purpose. So WTPF can play a key role in shaping the world's ICT long-term development by leading the way to build infrastructure and the policy model to connect the non-connected and drive the development of emerging technologies from a digital economy while accelerating the achievement of the United Nations Sustainable Development Goals. There's no doubt that the world now is facing a very crucial stage with exponential growth in the use of digital technology and services. This can only be beneficial to humanity if the appropriate and effective policy and regulation are in place. The current five opinions that will be discussed in the WTPF are good examples of the collaboration and the crystallization of inputs from around the world. Together we will discuss how to back harness these emerging technologies to tackle the most surprising challenges, including COVID-19 pandemic and accelerate the achievement of 2030 agenda for sustainable development. Those five opinions of WTPF 21 addressing emerging technologies such as 5G, AI, IoT, big data and OTT will be further discussed, developed and enriched among the three working groups in the coming days. Digital connectivity and infrastructure are essential building blocks in the digital ecosystem and we believe that IPv6 justifies some special attention since it's crucial for broadband connectivity, IoT, multimedia and other digital services. This IPv6 adoption today is highly uneven globally. We see that a global collaboration is essential and indispensable to take action to complete a global IPv6 deployment and more important to avoid the global IPv6 network being reduced into a series of IPv6 islands. So once again I would thank you very much for all the senior officials around the world, distinguished guests, Secretary General, Mr. Ho Ling Zhao and other members of ITU leadership, all the ITU staff members and all the participants today. It's your joint effort that made this meeting happen. So we are looking forward to a very successful and productive three-day meeting. So also Huawei and our experts will take active part in the following discussion. Once again thank you very much all Madam Chair.
