China at LHC Institutional participation Resources of Fund Zhengguo Zhao On behalf of Chinese LHC community University of Science and Technology of China Institutional participation Resources of Fund Upgrade program Summary

Welcome to China On behalf of Chinese High Energy Physics Association(CHEPA), welcome all of you to participate the LHCP 2017 here in Shanghai. Wish the conference to be very successful, and wish you all have a wonderful time in China

Congratulations from Chinese Funding Agencies to LHCP 2017 NSFC: Bureau of International Cooperation, Department of Mathematics and Physics Sciences CAS: Bureau of Frontier Science and Education, Bureau of International Cooperation Dear LHCP participants, It's our pleasure to welcome all of you to come to China for the LHCP 2017. We are well aware of the very successful operation of LHC and the fruitful results produced from all the experiments at LHC, of which they are closely related to find the answers to the key science questions of our century. We believe that LHC will be a unique frontier of high energy physics in the next decades to come. We will continue supporting LHC experiments, assuming that our scientists from China to LHC are strongly competitive, which we cherish the hope that they are able to. We wish LHCP 2017 is going to be very successful, and believe that more important physics results, as well as more leading scientists could be produced at LHC. MOST: Committed to support LHC experiment through different programs, e.g. The National Key Research and Development Program, The International Cooperation program…

Summary China has participated to ATLAS/CMS/LHCb/ALICE at LHC. The institutions and participants to the experiments has been expanding. We has been improving our own organization and performance: more active, more people to work at CERN, more involved in R&D, commissioning and physics analyze, annual CLHCP…. As the fast expanding to the participation, our contributions to both physics, commissioning and upgrade programs are enhancing. Fund for LHC in the next 5 years is secured at current scale, and Chinese funding agencies are committed to continue support LHC. LHC experiments are not only the frontier of HEP, but also the best foreground of R&D for future project (Fcc, CEPC….)
