"In China, they started on limited economic reform first but it was beginning to succeed in producing more goods for the people—on a limited scale certainly, but it was beginning to succeed. You cannot get economic reform really going well and with a future unless you get political liberty. That was what they found. We have always known it. Here, I think it was perhaps the wiser way to start: to start with the political reform, the thorough discussion. After all, new ideas come out of discussion and free interplay of ideas and discussion between one and the other. The glasnost as it is called, has gone very far very quickly, far further, far faster than we thought and I think that plus the communication of the ideas will in the end lead to much greater prosperity. I think the point that I have to make again is that although the politicians at the top—led by Mr. Gorbachev—could bring about the glasnost, it requires the practical and willing cooperation of the people to enlarge their responsibility and their activity to bring success in economic reform. I believe that will come about. I believe that the changes—the glasnost—really have become permanent because they have gone so much further than anything we thought and they have given a so much better atmosphere and less tension—the fear seems to have gone—and so I believe that perestroika is now set upon its course and that it will go through to success."
