The "fear of China" in Australian political circles and public opinion has become increasingly serious. One embodiment is the transformation of Australia's defense posture, which imagines China as a "clear and realistic danger". A recent poll shows that nearly 10% of Australians believe that China will "launch a military attack against Australia" in the near future. The other is reflected in the public opinion in Australia. Australian media often associate local Chinese and overseas Chinese with the "China Threat Theory". Behind the absurd "fear of China", the deep historical, cultural and socio-economic roots are worth pondering. Tracing back to the source, the "fear of China" of Australian political elites is a heartache. Australia, which regards itself as a western country, is undergoing a deepening and irreversible "Asianization" transformation. However, although Australia is geographically close to Asia and closely connected with the development of Asia, its political, cultural and identity roots are western. Its "Asianization" transformation process has brought strong cognitive impact and psychological contradictions, which has become a major incentive for "fear of China". Western racism and the "white Australian consciousness" are rooted in Australian history, and Asia has long been regarded as a backward "other". As early as the gold rush in the mid-19th century, Australia, still a British colony, had resisted Asian gold miners and set off a wave of "anti China" racism. The first piece of legislation of the Australian federal government established at the beginning of the 20th century included the Immigration Restriction Act, which restricted the entry of non European immigrants and regarded Asian immigrants, mainly Chinese, as a "yellow peril". This later widely known "White Australia Policy" was officially abolished only in the 1970s. After World War II, Australia gradually faced the reality of being in the Asia Pacific region and realized the importance of symbiosis with its Asian neighbors. In the 1980s and 1990s, Australia enthusiastically proposed to "integrate into Asia" for better development. In 1993, then Prime Minister Paul Keating announced that Australia would no longer be "a branch of the (British) Empire" and needed to "fully integrate into Asia". However, Australia's "Asianization" is selective: it is most interested in the Asian market and high net worth and high-tech immigrants, but has little interest in political and diplomatic exchanges. After decades of "Asianization", Australia has been integrated into Asia as never before in terms of economic and trade exchanges and population composition. In terms of economy and trade, in 2021, 12 of Australia's 15 largest trading partners will be Asian countries and regions. Chinese Mainland accounts for nearly 30%; This share is far higher than that of the second place US (9.3%) and the third place South Korea (9.1%). In terms of population composition, according to the latest census data in 2021, immigrants account for 27.6% of the total population of Australia, of which the proportion of Asian immigrants is rising. Chinese people have become the fifth largest group, accounting for 5.5% of the total population of Australia. For Australia, "Asianization" is an established fact and the direction of future development. However, because the identity, national consciousness and way of thinking of their political elites have not been adjusted with the current development and future trends, the process of "Asianization" has brought a strong psychological and emotional impact on Australian political elites who retain the sense of colonial culture and institutional superiority, which is another aspect of their "fear of China"
