Why China may reject Russia's Leader destroyer designs

Why does China repeatedly avoid Russia's proposed Leader-class destroyer designs?

The tentative explanation is that the design fits Russian operational concepts but not China's naval doctrine, despite China's willingness to borrow other foreign ideas.

A viewer describes Russian design bureaus continuing to update and market large Leader destroyer concepts despite limits on construction capacity. The comment argues that building such ships would require major infrastructure investment and training a new generation of engineers. China is said to have repeatedly declined the Leader designs despite its willingness to adopt and modify other foreign ideas. The reason for that rejection is uncertain. One tentative explanation is that the design reflects Russian assumptions about naval operations and global warfare that do not fit China's concept of war.
