(CNN) -- As anti-Japanese protests roiled dozens of cities across China over the weekend, Chinese state media has stepped up to condemn the violence, calling instead for "rational patriotism" to address the intensifying dispute over islands in the East China Sea.
While some protests were orderly, others spawned looting and vandalism of Japanese businesses and Japanese-made cars, as well as attacks with eggs and plastic bottles on the Japanese embassy in Beijing.
While acknowledging that the "expression of patriotism" over the weekend was a "reasonable move and natural reaction toward the provocation from the Japanese side," an editorial in the state-run Xinhua news agency cautioned on Monday that "the Chinese people should be rational and obey the law when expressing patriotic feelings, and they should abstain from 'smashing and looting.'"
"Wisdom is needed in the expression of patriotism," it added, which "should not come at the cost of disrupting domestic social order."
Similarly, a front-page article entitled, "Use Civilization and the Rule of Law to Consolidate Patriotic Force" in the Communist Party mouthpiece, People's Daily, praised the weekend's "patriotism" as "precious" and needing to be adequately cherished and protected."
"But being civilized, law-abiding is a basic quality of citizens. Damaging fellow citizens' legal property and taking out anger on Japanese nationals in China is extremely inappropriate," it admonished.
"In the age of globalization, we should let the world see a China that is peacefully developing, whose government is making progress and whose people are improving their qualities." People's Daily went on to conclude that patriotism needed to be expressed in a "reasonable and orderly way."
Chinese citizens, media, and the government also chimed in on the popular Sina Weibo microblogging website, where the "patriotic protests" have been the top trending topic.
User XiaoGuNaiNai opined: "Chinese people are too irrational, looting everywhere in the name of patriotism. In the end, don't we have to clean it all up ourselves, allowing the Japanese to laugh at us? If you have problems, take them to Japan. Smashing, burning, and destroying our surroundings only hurts the Chinese people!"
"The Sino-Japanese economic war has already officially begun. I hope it won't end in a situation where everyone loses," posted Wang Fuzhong, a popular economics scholar at the Central University of Finance and Economics.
The Southern People Weekly magazine also cautioned: "Vandalism in the name of patriotism is a felony," adding that destroying property and infringing on the rights of others did not make for a "civil and lawful society."
Guangzhou city police posted a call on its official Weibo account for netizens to photograph vandals and submit their photos to police for a reward.
The protests were triggered by the Japanese government's announcement last week that it had purchased several of the disputed islands from a Japanese family to bring them under public ownership.
The move was the latest flashpoint in a long-simmering dispute over control of the uninhabited islands, which are known in China as the Diaoyu Islands, and in Japan as the Senkaku Islands.
