Two years ago, China triggered an “Excellence Action Plan” to help China-based STM journals further enhance their international impact. In 2019, 20 journals were selected as "leading journals" and will be charged with the goal of ranking among the world’s top STM journals within 5 years. Besides those, 30 "key journals" and 200 "emerging journals" were selected to improve international editorial practices, service capabilities, international communication, etc. Furthermore, for each year between 2019 and 2023, China will choose and launch 30 new titles as “high potential journals” based on China’s priority research fields. This presentation will introduce more details and some achievements of this ambitious plan.
