Why are Chinese submarines getting bigger and bigger?

Since the new century, miniaturization of submarines seems to have become a new trend. Many countries, led by the United States, have begun to launch their own small submarines, and some countries have even tried their best to change nuclear submarines into boats capable of carrying small submarines. However, China, on the other hand, has failed to keep up with this trend. The submarines used by its own navy are getting bigger and bigger. Why?

The displacement of the early Type 33 submarine in China was only 1,8 tons, but it was raised to 2,1 tons in Type 35 and 3, tons in Class 39. At present, the standard displacement of Class 93 underwater is 6,8 tons, while Type 94 is over 11, tons, so it is an indisputable fact that China submarines are getting bigger and bigger. So, does this mean that China will not miniaturize its submarines just by blindly developing into big ones? In fact, China Navy had explored small submarines as early as 195s, but finally found that small submarines were not suitable for China Navy at all, so it gave up.

China's navy submarines need about 1, kilometers for offshore defense, but hundreds of tons of small submarines can't meet the mission requirements of our navy at all, and the recent craze for small submarines is actually for other countries to meet the needs of special operations, mainly for transporting special forces. Therefore, the China Navy, which mainly needs the traditional naval tasks, actually does not need to be equipped with such a small submarine. If it just pursues the trend blindly, it will only give up the basics and delay the development of its own equipment.

Although China's navy is not equipped with small submarines, it doesn't mean that China doesn't have the technical and economic ability to produce such equipment. In fact, China's military industry has already produced such equipment and pushed it to the international market for countries in need to purchase it. Therefore, China's navy is not equipped with small submarines, which only means that our navy doesn't need it now. If necessary, it may be equipped immediately.
