  High field superconducting magnets are crucial for high-energy particle accelerators. IHEP (institute for High Energy Physics, Beijing) is pursuing critical technologies R&D for future circular colliders like the Super Proton Proton Collider (SPPC). SPPC will need thousands of high field (12-20 T) superconducting magnets in around 20 years. A long term R&D roadmap of the advanced high field magnets has been made, aiming to push the technology frontier to the desired level, and a strong domestic collaboration is established, which brings together expertise of Chinese superconductivity community from fields of materials, physics, technology and engineering. The goal is to address prominent scientific and technological issues and challenges for high field applications of advanced superconducting materials. In the past year a model magnet with hybrid coils (NbTi and Nb3Sn ) has been manufactured and tested, reaching a dipole field above 10 T in the two apertures. A full Nb3Sn model has also been fabricated and tested with a coil made of iron based superconductor inserted in the center. An overview of the high field magnet program, R&D status and the future plans will be presented.
