On March 1 Beijing time, US President Donald Trump issued his first congressional speech since the inauguration in the Congress, mainly focusing on economic and trade policy, with emphasis on domestic issues, pushing for US economic growth through tax reform, $ 1 trillion in infrastructure spending and rectification of the Obamacare. On international trade, he stressed that the United States will implement a very high tariff, and reiterated the decision to withdraw from the TPP. As for immigration policy, Trump said he was open to the overall reform of the US immigration system and would implement a new immigration system to regulate new immigrants to the United States and reduce the flow of low-skilled migrants. We notice that Trump still repeats the claims he mentioned before without sufficient details.
