We consider Yang–Baxter equations arising from its associative analog and study the corresponding exchange relations. They generate finite-dimensional quantum algebras which have the form of coupled &${\rm{GL}}(N)$; Sklyanin elliptic algebras. Then we proceed to a natural generalization of the Baxter–Belavin quantum R-matrix to the case &${\rm{Mat}}{(N,{\mathbb{C}})}^{\otimes 2}\otimes {\rm{Mat}}{(M,{\mathbb{C}})}^{\otimes 2}.$; It can be viewed as symmetric form of &${\rm{GL}}({NM})\;$; R-matrix in the sense that the Planck constant and the spectral parameter enter (almost) symmetrically. Such type (symmetric) R-matrices are also shown to satisfy the Yang–Baxter like quadratic and cubic equations.
