The Chinese Agriculture Technology Demonstration Centre (ATDC) in Ethiopia is an aid project on agricultural technology cooperation between China and Ethiopia. The process of cooperation is the art of improvising on the ground when the original project plan doesn’t quite match reality. This study analyses the logic behind the improvising of implementation on the ground. It found that the running of this project is not following project management procedures and log-frame indicators but is instead based on the experiences of agricultural extension in China. Through Chinese experts, as individual actors, ATDC brought in the approach of top-down planning, assumption of package support and integration of commercial functions which can be found in the reformed extension system in China. The Chinese experts carry this working approach – along with its assumptions and principles – to Ethiopia, without considering the lack of any parallel institution and culture there at the beginning. This results in many challenges for implementing the ATDC activities and novel reactions by the ATDC experts, which also reflect the individual’s working style in the Chinese extension system. Though the technologies are still present inside the ATDC after many efforts, a request to extend the cooperation phase from the Ethiopian side implies an appreciation of the approach and its results to some extent.
