Complete agree. The LDP has all but announced they have chosen to sacrifice their population's purchasing power in order to inflate the stock market and boost their business sector via exports. Their second biggest export partner is China at 19%, only 2% behind the US. China can make it hurt for the LDP by attacking via this vector so that the sacrifice they decided to accept becomes completely voided and pointless at the end of the day.
In addition, China should do comprehensive studies on Japan's sectors of export they have an advantage in and explicity target either their other customers with alternatives of better value or more subsidizing R&D and production in these sectors especially to catch and beat them. The end goal should be the DESTRUCTION of the Japanese high value chain export capability FOREVER. Japan's primary exports should be trinkets, fish and plane tickets for men to visit their "pleasure" industry, ONLY.
It gets worse. Just look at what China exports to Japan:
Japan has always been very resistant to buying inexpensive goods from China (and their economy has probably suffered for doing so), so these kinds of products don't count for very much of what Japan imports. Instead, what they buy tends to be machinery and other industrial inputs that are essential for Japan's economy. These goods are indispensible and very difficult to acquire in quantity from other sources. And if there are other producers, the prices are going to be a lot higher, and that's disaster for Japan's already teetering economy.
On the other side, it's just as bad. Most of what Japan exports to China can be either made in China itself, or are products to Japanese-owned factories in China. For example, Toyota is planning to produce 2.5 million cars in China by 2030; guess where a lot of these industrial inputs are going to come from? There are a million ways to disrupt this if China were to choose to. And of course, the point comes back to Japan's one major success story is the automotive sector, and China is already starting to eat that particular pie.
Overall, it's an asymmetrical relationship, and Japan's economy and general living conditions are already in trouble. There are so many ways for China to make Japan suffer, and the beauty is that the people behind Takaichi's soaring approval numbers have no idea what's about to happen.
