Today marks the 25th anniversary of the signing of the Peace and Friendship Treaty between China and Japan.
The treaty proclaimed that both countries would 'develop relations of perpetual peace and friendship', but they have shown little enthusiasm for celebrating the year so far - no large-scale commemorative events, no outpouring of warm feelings and no plans for a Sino-Japanese summit.
But it was very different 25 years ago. In 1978, Chinese Vice-Premier Deng Xiaoping, who had just consolidated his position as China's paramount leader, took 70 delegates to Japan to mark the treaty's birth - the highest level of Chinese leadership ever to visit Japan at that time. But the road to reconciliation between the two countries has been bumpy and often scattered with barriers. In fact, a number of 'f' words may well capture the state of Sino-Japanese relations in this period.
Friend or foe? Few bilateral relations in the world have used so much official rhetoric on friendship as China and Japan in the past two- and-a-half decades. Indeed, the close economic interdependence of the two has gone far beyond the expectations of the generation who signed the treaty. Japan is China's largest trading partner while China ranks first in Japan's foreign trade. Japan has provided well over 50 per cent of China's total foreign development aid, and the amount of Japanese investment in China is second only to that of Hong Kong.
Yet such deepening economic ties have not translated into enhanced friendship, despite the fact that hundreds of thousands of Japanese and Chinese now work and live in each other's countries; and that millions of people from both sides have visited the other.
In a survey in 1980, 79 per cent of Japanese chose China as their favourite country, overtaking the United States. But today, more than 50 per cent of Japanese say they don't feel friendly towards China. And in a recent poll, more than 80 per cent of Chinese respondents had a negative impression of Japan.
So the standard liberal theory that increased interaction between peoples will lead to mutual understanding and co-operation does not seem to fit in this case. Some point to Japan's growing power in the 1980s and the rapid modernisation of China since 1990 as mainly responsible for problems in bilateral relations. Currently, many in both countries see each other's expanding military capabilities as a potential threat. Rather than talking friendship, the two nations often look to history for the roots of their rivalry.
