which best describes how dengs move to work with international experts on matters of science and technology was a major departure from previous government policy in china? china had had a policy of self - reliance. china had refused to embrace modern technology. china had established local teams of experts. china had been closed to most foreigners.

Explanation:

Before Deng's move to work with international experts on science - tech, China had a long - standing policy of self - reliance. Working with international experts was a departure from this self - contained approach. The other options are not as accurate in representing the major policy shift. China did not completely refuse modern technology before, and having local expert teams was not the main contrast. Also, being closed to most foreigners is not the most direct contrast to this new policy in the context of science and technology cooperation.

Answer:

China had had a policy of self - reliance.
