BEIJING (AP) — President Xi Jinping tended to huge bouquets and gunners fired salutes Wednesday as China commemorated Japan's World War II surrender in a campaign to remind the world of Tokyo's historical aggression amid tense ties between the countries. China's angry rhetoric about Japan spiked two years ago when Tokyo nationalized a group of East China Sea islands also claimed by China, and has been exacerbated since then by Japanese politicians' visits to a Tokyo shrine honoring war dead and remarks seen as minimizing Japan's war guilt. The commemoration activities, broadcast on state television along with interviews with Chinese recollecting their experiences of the war, are expected to sharpen anti-Japanese feeling in China, where the Communist Party uses nationalism to shore up its rule. Authorities have ordered TV stations to air shows with anti-fascist and patriotic themes in prime time from Wednesday until the end of October, according to local media reports.
