Now that Prime Minister Shinzo Abe has visited Pearl Harbor with U.S. President Barack Obama in a show of reconciliation between the two World War II foes, a U.S.-based Chinese scholar has suggested that Abe take a step further to achieve rapprochement with China over wartime history.

Zhao Quansheng, a professor of international relations at American University, saw Abe's visit Tuesday to the site of Japan's 1941 attack on Hawaii and Obama's preceding trip to atomic-bombed Hiroshima in May as "a win-win for both countries."

Zhao is now recommending that Abe visit Nanjing, the site of the 1937 killing by the Japanese military of Chinese civilians and soldiers and a symbolic place of Japan's wartime aggression against China.
