Abstract	Belle II offers unique possibilities for discovering and interpreting exotic multiquark bound states to probe the fundamentals of QCD. This talk presents recent results on a unique data set collected at energies above the Υ(4S), including searches for the hidden bottom transition between Y(10750) and 𝜒𝑏𝐽 and measurements of the energy dependence of the 𝑒+𝑒−→𝐵(∗)𝐵¯(∗) cross section. Recent Belle results on quarkonium will also be shown.
