What are the leading areas of "blocking foreigners' necks" in China?

China leads the world in the following fields, known as "choking foreigners": civil unmanned aerial vehicle, quantum communication technology, high-speed rail technology, 5G technology, gantry crane, UHV transmission technology, rare earth and bridge construction technology.

First, civil drones:

China's DJI UAV occupies 74% of the global market share, and it can't find competitors with equal strength in the same field;

Second, the quantum communication technology:

China has completed thousands of kilometers of secret communication without relay, leading the world, and countries such as Europe, America, Japan and South Korea have not reached this level at present;

Third, high-speed rail technology:

In the field of high-speed rail, there are 245 important standards for high-speed rail, of which China standard accounts for 84%. High-speed rail has become a business card of China, which has been recognized by the whole world. The high-speed rail made in China is safe, comfortable and fast. At present, our Asian neighbor Japan can compete with China in the field of high-speed rail, and most of the high-speed rail orders in the world are basically monopolized by China and Japan;

Fourth, 5G technology:

There are four manufacturers of 5G equipment in the world, with China occupying two seats, namely Huawei and ZTE, and the other two are Nokia and Ericsson. Among them, there is a big gap between China Huawei and the other three competitors, and China Huawei ranks first in both the number of core patents and the market share of 5G equipment. It is Huawei's leading position in 5G technology that led to the US sanctions against Huawei.

5G is the integration of most top technologies in the world, and there will be countless 5G products derived from 5G technology. If Huawei in China formulates 5G communication standards in the future, any technology or product of 5G may be stuck on the neck of Americans;

Five, gantry crane:

More than 90% of the world's large shipyards use gantry crane technology from China, and even American aircraft carriers must use gantry cranes from China when assembling, because the gantry cranes produced by the United States cannot meet the lifting tonnage required in the assembly process of aircraft carriers;

Transmission technology of intransitive verb UHV;

China's UHV transmission technology standard is the only standard in the world, and the word "unique" means that China has no competitors in this field;

Seven, rare earth:

In 20 19 years, China occupied 62.86% of the global rare earth mining volume. What needs to be emphasized here is that rare earth is a strategic resource. Most of the world's rare earth reserves are in China, and all kinds of high-end electronic equipment parts can't be manufactured without rare earth. In the future, the strategic importance of rare earth is no less than that of oil;

Eight, bridge construction technology:

China's bridge construction technology is called "one of the seven wonders of the new world", and the most representative one is the Hong Kong-Zhuhai-Macao Bridge. China can't find qualified competitors in the field of bridge construction technology, and it is basically crushed.
