The Chinese state-run news media have stepped up their hawkish tone since the episode. On Mr. Abe’s trip to Southeast Asia, which the Chinese say is intended to create a pro-Japan alliance, the overseas edition of The People’s Daily newspaper said, “Even the United States, the world’s sole superpower, acknowledged that it cannot encircle and contain China, so why should Japan?”
Chinese experts express similar views. In an interview, Hu Lingyuan, the deputy director of the Center for Japanese Studies at Fudan University in Shanghai, described Mr. Abe as a Japanese nationalist who was trying to overextend Japan’s reach. “The Diaoyu conflict keeps escalating,” he said. “A solution is not possible.” And as the commentary became harsher, the Chinese news media stressed reports of training by the military’s East China Sea units. Dozens of J-10 fighter jets participated in a live ammunition drill with the Navy’s East China Sea Fleet, the state run news agency, Xinhua, reported Thursday.
Before returning to Japan, Mr. Abe spoke to reporters in Jakarta, Indonesia. He said he opposed “changing the status quo by force,” and called on China to behave in a responsible manner.
“The seas is a public asset that should not be governed by force but by rule of law that keeps it freely open to all,” he said. “We will work with Asean nations to do our utmost to defend this.” Asean refers to the Association of Southeast Asian Nations.
With a top United States diplomat, Kurt M. Campbell, in Tokyo this week, Washington is urging both sides to open a dialogue.
But the initial signs are not particularly promising. On Thursday, a former Japanese prime minister, Yukio Hatoyama of the opposition Democratic Party, met in Beijing with Jia Qinglin, the chairman of the National Committee of the Chinese People’s Political Consultative Conference.
The setting looked conciliatory. China, however, used the occasion to make a point that was immediately rejected in Tokyo. Mr. Jia called for talks with Japan over the disputed islands, an idea that Japan has always said was unacceptable. Japanese governments have consistently maintained that the islands rightfully belong to Japan and that there is nothing to discuss.
