Gasgoo.com (Shanghai) - With tensions rising over the disputed Diaoyu Islands, waves of protests endorsing the boycott of Japanese goods have been flaring across China. The effects of these activities have taken their toll on sales of Japanese branded products, including automobiles, in the country. Various reports highlighting declining Chinese sales of Japanese vehicles have been circulating through the media throughout the month. China's Ministry of Foreign Affairs has gone as far as warning Japan to stop 'harming Chinese territorial interests' in order to prevent further economic damage to its enterprises.
