The purpose of open policy is to acquire advanced technology, management skills to serve our socialist construction so as to promote the realization of the four modernizations.
We must adhere to the open policy. Because economic relations between states today have become increasingly close, and no country can possibly advance behind close doors. Only in this way, can we gradually close the gap between our country and the developed countries.
Through the implementation of policy, we can learn advanced technology and managerial expertise from abroad; make full use of the foreign capitals to set up great enterprises; absorb useful and healthy ideas and new knowledge of the modern civilization; and broaden our views and raise our level of competence.
