This paper studies the science communication activities by foreign embassies in China from perspectives of the agent, content, purpose, form, audience and duration. by taking six embassies as the main representatives. This research finds that science communication activities by foreign embassies in China tend to focus on their own strong scientific research areas or their citizens with global influence. The activities carried out are mostly one-time activities. Media training program is highly noted by the foreign embassies. The findings show that the purpose of the science communication activities by foreign embassies is to publicize their science strength and to sell their science images rather than enhance the comprehensive scientific literacy of Chinese citizens. The benefits gained from these activities also provide certain countermeasures and suggestions for science communication activities in China.
