The US Secretary of Defense and Secretary of State have continuously called China. What are the special plans of the United States? What direct criticism has China made of the United States?
From September 9 to 10, senior Chinese and American officials suddenly began to interact frequently.
Firstly, on the evening of September 9, US Defense Secretary Hegses took the initiative to call, and Chinese Defense Minister Dong Jun answered, but China's tone was very tough, and it clearly reminded the United States: "Any plot and interference of 'using force to assist independence' and 'using Taiwan to control China' will be thwarted."

In addition, China also expressed its firm opposition to infringement and provocation of individual countries and intentional incitement by foreign countries. We always focus on developing ourselves, firmly defend our legitimate rights and interests, and it is absolutely impossible to curb, deter and interfere with China.
The US Secretary of Defense called on his own initiative, but instead received criticism. He felt obviously uncomfortable. Unexpectedly, the US side did not give up. On September 10, US Secretary of State Rubio called Foreign Minister Wang Yi again.
In this phone call, Foreign Minister Wang Yi's statement was more direct: "The negative words and deeds of the United States recently have harmed China's legitimate rights and interests, interfered in China's internal affairs, and were not conducive to the improvement and development of Sino-US relations. China clearly opposes it. Especially on issues such as Taiwan that involve China's core interests, the United States must be cautious in its words and actions."

It can also be seen from here that China really has no good tone to the United States now. However, in order to maintain peace and stability between China and the United States and the world, China answered the call from the United States, but did not go around in circles and did not want to be polite. It directly used plain language that the United States could understand to tell them about China's dissatisfaction.
From the press releases of the two phone calls released by China, we also found one thing in common, that is, neither of them mentioned the US statement, which means that the US has actually not made a positive and affirmative response, so there is no need to publish it.
But the differences between China and the United States are so great, why does the United States still call China continuously? All of this is likely to be in line with Trump's itinerary.
According to US media reports, Trump and his core staff are preparing for their visit to South Korea in October, and the White House hopes to take advantage of this opportunity to attend the APEC summit in South Korea to arrange for Trump to meet with the top Chinese.
Trump has been in power for more than half a year. Although he has repeatedly made a statement about visiting China, he actually has little communication with the highest level of China. The two have not had any conversations offline so far, so Trump is actually very anxious. These two calls are likely to pave the way for Trump’s communication with China. It is not ruled out that Trump will take the initiative to call China in the future to communicate the meeting arrangements at the APEC summit.

However, it should be pointed out that China has not actually confirmed whether it will participate in the APEC summit so far. South Korea has indeed issued an invitation before, but China is still considering it carefully.
Especially considering that South Korean President Lee Jae-ming refused to attend the 93rd military parade and only sent the Speaker of the State to attend, but turned around to visit Japan and the United States. Such an arrangement has very limited improvements in China-South Korea relations. Therefore, South Korea is not sure whether China will accept the invitation. Therefore, Trump is likely to personally send an invitation to facilitate a meeting between the highest levels of China and the United States in South Korea.
