This topic mainly investigates the acquisition of trademark rights. Paragraph 2 of Article 18 of the Trademark Law stipulates that foreigners or foreign enterprises applying for trademark registration and handling other trademark matters in China shall entrust a legally established trademark agency to handle them. Therefore, item A is wrong.

Article 17 of the Trademark Law stipulates that if a foreigner or foreign enterprise applies for trademark registration in China, it shall do so in accordance with the agreement signed between his country and People's Republic of China (PRC) or the international treaties to which * * * is a party, or in accordance with the principle of reciprocity. Therefore, it is not necessary for the country to join the Paris Convention for the Protection of Industrial Property or the World Trade Organization. Even if you don't join these conventions or organizations, you can be protected according to the principle of reciprocity. Therefore, items B and C are wrong. Trademarks are regional or independent, that is, whether a country grants trademark registration is an independent judgment and decision made by the country's trademark authorities according to the country's trademark law, and is not necessarily affected by the country's decision. Therefore, item D is correct.
