1930年代,“标准石油”产品在华营销,遭遇广东地方政府歧视性关税待遇,以及日本操纵下的满洲国地区石油产业垄断。美国以“门户开放”条约权利受损为名,与石油企业合作维护国家利益,首次形成美国在东亚地区官商合作的特殊外交模式。 In the 1930s, “standard oil” products were marketed in China, which suffered discriminatory tariffs from local governments in Guangdong and the monopoly of the oil industry in Manchukuo under the control of Japan. The United States, under the pretext of undermining the “Open Door” treaty rights, cooperated with oil companies in safeguarding the interests of the country and for the first time formed the special diplomatic mode of U.S. official and merchant cooperation in East Asia.
