Best time to discuss the bilateral trade cooperation As far as I am concerned, Premier Wen＇s visit to Japan is so successful and even out of my expectation. The Joint Communique promulgated by the two sides is so detailed and with such a wide coverage, the content is so rich, that I think it must be an unusual effort by the two governments. It is also my heart-felt touch that in order to ensure the success of the visit, Premier Wen has made tremendous efforts by himself.

At the invitation of the Japanese government, from April 11 to 13, Chinese Premier Wen Jiabao paid an official visit to Japan, which was described as an 'ice-thawing journey', and launched talks with Japanese Prime Minister Shinzo Abe. During the visit, both sides also inked a joint press communique, in which detailed measures to fresh out contents of strategic and mutual beneficial bilateral relationship have been included, marking a historic event of the bilateral relations between the two nations. Wen's successful visit to Japan, which occurred in the year of the 35th anniversary of the normalization of Sino-Japanese relations, received great concerns from the two peoples and the world community and was of far-reaching significance concerning the longstanding friendship between the two peoples and the steady development of China-Japan bilateral relations in both politics and trade. On April 19,China's Foreign Trade had an interview with Takeo Donoue, Counsellor of Embassy of Japan in China, on the discussion of promoting the sound development of Sino-Japanese economic and trade relations on this critical historic moment. Takeo Donoue told us that both the Japanese government and its economic community have been looking forward to faster progress of the economic and trade ties between the two sides.

日本学者在比较研究上往往以“三元比较”而展开,主要是在日本、中国、西方之间进行比较。加藤周一是这种比较方法的佼佼者。综观20世纪,二元研究方法是比较文学/诗学的常用方法,但它具有笼统性、静态性和对立性,三元比较有可能走出二元研究的困境。加藤周一的比较诗学有两个意图,一是确立日本特色,二是探寻普遍标准。前期加藤周一认为日本特色是“杂种文化”,后期加藤周一认为日本特色是“现在=此处”文化,后者是对前者的具体化、深入化和学理化。在时间和空间问题上,加藤周一都实施了三元比较方法。“确立日本特色”之后,还要“超越日本特色”。因为文化特色往往就是作为过去时和完成体的传统文化的特色。加藤周一的比较诗学却要走出传统,走向现代。进入20世纪之后,世界一体化,传统文化的特殊性与现代文化的普遍性存在冲突。文学和艺术的普遍标准何以可能?比较诗学不能预设普遍人性论,必须经验性地探寻普遍标准。现代和国际是外部条件,语言(的普遍有效性)是内部条件。现代、国际、语言三者缺一不可。世界一体化裹挟着“艺术只有一个”的思维观念。既然如此,艺术普遍标准的存在便是理所应当的了。
