Gravitational-wave Excellence through Alliance Training (GrEAT) Network with China The breakthrough discovery of gravitational waves (GW) - propagating distortions of space-time - by Advanced LIGO in 2015 confirmed the last major untested prediction of Einstein's General Theory of Relativity. The announcement made headlines world-wide and further accelerated interest in GW research in China.  There is a significant opportunity for the UK GW leadership and expertise to play a major role in shaping the course of GW research in China. Our vision is to build a connected international network, enabling China to host the most-sensitive international GW detector. The UK has a proven track record in delivering high-quality technology/outreach activities relating to GW science, including the delivery of key subsystems for Advanced LIGO. The main impact of the proposed network will be to build up technical capacity and capability in China across a broad range of disciplines relating to the detection of GWs through the application of UK expertise. The proposed training network will be the first step in growing the GW community in China to the point where they can design, construct and run major research infrastructures in the form of GW detectors. The training network will also help the Chinese scientific community become a major international player in the emerging frontier of GW astronomy.  The proposed training network will bring together the UK GW consortium with eight universities in China, with whom members of the UK consortium have had initial contact. These eight universities are Beijing Normal University, Changchun University of Science and Technology, Huazhong University of Science and Technology, Hubei University of Education, Shandong University, Sun Yat-Sen University, Tonji University and Tsinghua University.  This training network aims to address the UN Sustainable Development Goals of Quality Education, Industry Innovation and Infrastructure, and Decent Work and Economic Growth. In addition to gravitational wave training activities, the training network will also organise workshops where UK GW teams can showcase their technologies to potential industry partners in China. Initial efforts have identified Shanghai Jillion, Nantong PRTT and the National Supercomputing Center in Wuxi as possible multi-disciplinary, industry collaborators in China.   We will also promote STEM education through the development of resources suitable for both formal and informal learners - in the latter case, in particular, supporting the emergent plans for a Science Education Centre in China - and, building upon our extensive Education and Public Outreach leadership experience within LIGO Scientific Collaboration, producing high-impact exhibitions, multimedia, citizen science projects and online materials. We will also exploit our considerable experience on the steering group of the STFC-funded community outreach project Dark Sky Discovery (initially Dark Sky Scotland), adapting to the Chinese context the successful dark sky model for using basic astronomy to convey key messages to rural communities that have little science capital. The Global Challenges Research Fund (GCRF) supports cutting-edge research to address challenges faced by developing countries. The fund addresses the UN sustainable development goals. It aims to maximise the impact of research and innovation to improve lives and opportunity in the developing world.
