China chooses periodic blockades or air-sea coordinated exercizes around Taiwan's 12 mile waters as a strategy to respond to US Indo-Pacific strategy of keeping lanes of sea traffic and navigation on oceans open to all nations. This is seen as less risky than an outright invasion. Military exercises in August 2022 are seen as preparing for such a strategy. The US is the destination for $541 billion and Europe $521 billion in products Made in China in 2021, which make China the manufacturing powerhouse in the world. Without the export of $1 trillion in Chinese products thousands of factories and millions of Chinese workers would remain idle. It is unbelievable that China is risking so much with its Taiwan policy with no idea of what the consequences would be years from now. It took China three decades after the gradual opening by 1990 and a willingness on the part of American and European governments and business to give up much of their own manufacturing leading to loss of jobs in communities across both America and Europe and much pain from this loss, for China to get to $1 trillion in exports. This situation may never come back as the supply chains shift and jobs return home and to countries that are becoming competitive in infrastructure and capabilities in Asia. Such competition between nations is not unknown as it was with Imperial Japan in the Pacific just 100 years back. The US maintains its position as keeping navigation on the oceans of the world open and rule of law, and it is on these foundations that China was able to get the strong manufacturing and exporting position it has now that no nation has enjoyed in history to this extent. Only the British come close in the nineteenth century. So much of China's progress in the twentieth century was a result of cooperation and support from America, from the first university Tsinghua in Beiijing, to the war against imperialist forces of Japan, to the rebuilding of China's manufacturing and technological competitiveness with American business cooperation. ...
