Plastic guns in packaging which reads: "The Diaoyu Islands are China's territory", have been found on sale in a Hong Kong shop, it appears.
The islands in the East China Sea are currently controlled by Japan, but also claimed by China and Taiwan.
"It is extremely dangerous to link [a children's toy] to a territorial dispute and even war," Cheung Man-kwong of the Hong Kong Professional Teachers' Union told the South China Morning Post.
Despite the criticism, shop owner Peter Chan said he saw the issue quite differently. "I don't think the teenagers care about the slogan. They dump the packaging immediately after unwrapping the gun," he told the paper. He has sold approximately 20 of the guns - believed to have been imported from mainland China - to teenagers in the Kowloon area.
The Diaoyu Islands are the subject of a sometimes bitter territorial dispute between China, Japan and Taiwan and raise concerns over the increased militarization of the region. Sovereignty of the islands, known as the Senkaku Islands in Japan and the Tiaoyutai Islands in Taiwan, brings access to fishing grounds, shipping lanes, and the possibility of oil deposits.
