Sino-Japanese relations are facing their "toughest situation" since the two countries normalized ties nearly 30 years ago due to issues related to history, trade and Taiwan, new Chinese Ambassador to Japan Wu Dawei said Friday.
"This year, bilateral relations have seriously suffered from the two most sensitive issues -- those of history and Taiwan," Wu told the Japan National Press Club in Tokyo, adding economic and trade issues to the list of outstanding problems.
Wu urged Japan to take action to change the atmosphere between the two countries, but he did not elaborate when asked what conditions must be met for Prime Minister Junichiro Koizumi's proposed visit to China to go ahead before the Asia-Pacific Economic Cooperation forum holds its summit in Shanghai in October.
