Is 𘈐 Chinese?

No. It belongs to the Tangut script.

That script was devised around 1036 under Western Xia ruler Li Yuanhao for state-building, including a Tangut-language Buddhist canon. Tangut writing took visual and structural inspiration from Chinese characters without deriving from them; the Tangut court followed neighboring Khitan states, whose two scripts had appeared about a century earlier.

Later Tangut writing included Buddhist works, translations of Chinese books, and original literature. The latest known examples date to the late 15th and early 16th centuries; by the end of the Ming dynasty, the script was long obsolete.
