Why is Trump's executive order still being implemented? < / b > < / P > < p > [Global Times global network reporter Ni Hao] former US President trump has been "people walk tea cold", but the executive order issued during his term of office is still being implemented. On March 11, S & P global ratings announced that it would remove Xiaomi from the S & P Dow before the opening of trading on March 15. Earlier, another global index company, FTSE Russell, also said it would remove Xiaomi from the global index from March 12. < p > < p > on the 11th, Xiaomi's share price, which had risen 3.6% all the way up, went down on the Hong Kong stock exchange, and the whole day's rise was wiped out around 3 pm. < / P > < p > Zhao Qiuyan, a researcher of the machinist think tank, told the global times on the same day that in view of < span style = "box sizing: inherit; text decoration thickness: initial; text decoration style: initial; text decoration color: initial; "> Biden < / span > government has not made a decision to change or even abolish the relevant administrative orders of the previous government, so the above administrative orders are still valid and continue to be implemented. Lu Xiang, a researcher at the American Institute of the Chinese Academy of Social Sciences, explained to the global times that if the executive order issued by the previous president is not revoked by the Congress, the Supreme Court and the current president, the executive order will still be valid. Therefore, most of the economic and trade restrictions imposed on China during Trump's administration are still being implemented. On January 14, at the last moment of Trump's term, the US Department of defense "hacked" Xiaomi as a "Chinese military enterprise". On March 6, the Wall Street Journal revealed part of the reasons why Xiaomi was "hacked", including Lei Jun, CEO of Xiaomi group, who was "praised by relevant government departments" in 2019. < / P > < p > what is the relationship between Xiaomi being "pulled black" and being "eliminated" by index companies? < / P > < p > according to Zhao Qiuyan's introduction, in September 2019, including the United States < span style = "box sizing: inherit; text decoration thickness: initial; text decoration style: initial; text decoration color: initial; "> several members of Congress, including Republican Senator Tom cotton and Democratic Senator Schumer, asked the US Department of defense to restart section 1237 of the defense authorization act of 1999, in order to eliminate the worry that" China's civilian emerging technologies are used for military purposes ". According to the clause, < span style = "box sizing: inherit; text decoration thickness: initial; text decoration style: initial; text decoration color: initial; "> the president of the United States < / span > implements the sanctions authorized by the international emergency economic power act (IEEPA) without declaring a" state of emergency ". The scope of sanctions includes restrictions on investment and property transactions of enterprises on the blacklist. In June 2020, the US Department of Defense announced the first batch of Chinese enterprises to be included in the "blacklist" and the second batch in August, with a total of 31 Chinese enterprises in the two batches. < / P > < p > according to the authorization of section 1237 of the national defense authorization act of 1999, former US President trump signed executive order 13959 on November 12, 2020. After the 60 day period, that is, from January 11, 2021, Chinese enterprises on the "blacklist" will be prohibited from buying stocks. As of November 11, 2021, US investors will be required to clear and divest all these investments. The executive order was subsequently amended, and the U.S. Treasury Department, which implements divestiture investment, also revised the divestiture time of some enterprises through various departments' Q & A. Zhao Qiuyan said that article 1237 of the national defense authorization act of 1999 has a wide range of authorization. Trump's executive order 13959 finally referred to the previous relevant proposals of Republican Senator Rubio and decided to restrict the investment of these companies. On December 5, 2020, the US State Department claimed that some major index funds provided channels for US investors to invest in Chinese enterprises on the "blacklist", and named Minsheng MSCI and FTSE Russell. Subsequently, the US New York Stock Exchange, S & P Dow Jones and FTSE Russell took actions one after another to stop trading related Chinese companies or exclude them from relevant indexes. < / P > < p > the US approach has encountered strong opposition from China. The CSRC said that the US side implemented the administrative order for political purposes, completely ignoring the actual situation of the relevant companies and the legitimate rights and interests of global investors, seriously undermining the normal market rules and order. China's foreign ministry also believes that this move by the United States will undermine the confidence of foreign enterprises in investing in the United States, and will eventually harm the interests of American enterprises and investors. < / P > < p > in addition, the restrictions on Chinese enterprises in the financial field of the United States include the foreign company Accountability Act signed by trump on December 18 last year, which makes Chinese enterprises listed in the United States face the risk of delisting. But so far, Biden's government is still evaluating Trump's China policy and has not made any changes. < p > < p > < / P > < p > Lu Xiang believes that Biden will make relevant decisions after he has completed the evaluation of his China policy in less than two months. Lu Xiang said, "Biden should see the mutually beneficial economic and trade relations between China and the United States. Therefore, it is in the interests of the United States to adjust the wrong policy of the last administration to exert extreme pressure on China, and it is also worth looking forward to."
