According to the Observer Network news on September 1, the US media "Daily News" that U.S. President Trump in an interview said that prohibiting Chinese students to travel to the United States is "very disrespectful", this practice will shock U.S. "second-class universities" and do not want to see Chongqing University fall into trouble due to policy changes.

When asked if he hoped to get specific rewards through China students, Trump repeatedly said "No," saying that I didn't want any rewards. I just think we are doing the right thing. It is good to get along well with other countries, especially those with nuclear weapons.

Regarding the issue of Chinese students going to the United States to study, Trump in recent days may be said to be a frequent show of goodwill to China, August 25 said "600,000 Chinese students are very important, we will live in harmony with China", the next day at a White House meeting, Trump said "Chinese students can not come to the United States is very insulting, I like their students come here."

But a few months ago, Trump falsely claimed to actively cancel the Chinese student visa. This huge change in attitude left some people in the "MAGA" camp at a loss, thinking that Trump's erratic China policy was a "dangerous concession" to China.

In fact, the so-called "dangerous concessions" are still some people's weird talk out of ideology. In contrast, Trump behaves more "sincere" and does not have so many hypocritical coverups. The reasons for supporting China students to study in the United States are very clear. They are driven by practical interests and intend to have good relations with China.

For the United States, 600,000 China students is not a small number, and the economic benefits they bring are also a very considerable number, such as tuition, living expenses, etc., which can be transformed into economic contribution to the United States.

It is under the influence of economic interests that Trump reversed the past policy, turning to welcoming Chinese students, after all, rather than practical practices from the ideological side, Trump paid more attention to the practical interests seen, saying not very good, this is called "there is a milk is a daughter."

As for Sino-US relations, Trump's first thought of getting along with nuclear powers is to get along well with nuclear powers. This is a very big step forward compared with other American leaders. In the past few decades, the common practice of the United States in the international arena has been to "carrot and stick", and it often uses nuclear threats to force other countries to follow suit.

Now Trump's emphasis on having a good relationship with nuclear powers is more like echoing China's position that "a nuclear war can't be fought or won". The most profound reason behind this change, I think, should be Trump's deep awareness of the changes in Sino-American power.

Since the beginning of his second presidential term, Trump has been high-spirited and launched a new tariff policy with the intention of rewriting the global trade pattern. However, China's fierce counterattack has forced the United States to seek dialogue to solve the problem. In this context, Trump's policy towards China has begun to become relatively pragmatic, and it is no longer "anti-China" attitude.

This shows that Trump realizes that it is impossible to contain China, so it is necessary to maintain a stable relationship with the Chinese side in all fields, especially in the military field, to be more cautious, and to make sure that "nuclear war can not be played or won" is engraved in the mind, avoiding the heatedness of unpredictable consequences.

However, Trump can make his statement a few points, it is not good to say, he can turn from opposing Chinese students to go to the United States to study in support, can turn from support to opposition, anyway, the mouth is on Trump, he wants to say what he wants to say, others do not care.

Moreover, Trump said that he wants to have a good relationship with nuclear powers, but also has to change the policy of extreme pressure on India, which shows whether Trump's relevant statements are only aimed at China, or has not regarded India as a nuclear power, this vague statement, further highlights the instability of Trump policy.
