The analyses of states with double cs content and the search for exotics have recently gained much attention. The Belle experiment collected roughly 1 ab-1 integrated luminosity data. While Belle II data-taking is in progress, we have performed a new search for exotic states and cross-section measurements with the full Belle data sets. Here we review the recent analysis of: (a) e+e-→ Ds(*)++DsJ- + c.c. from both Υ(2S) decays and continuum production at 10.52 GeV, using the Belle detector at KEKB; (b) the analysis of e+e- → ηc J/ψ + c.c. and search for double charmonium states; (c) the study of e+e- → Ds+Ds0(2317)- + c.c. and e+e- → Ds+Ds1(2460)- + c.c. + anything else, in the continuum. Born cross-sections are evaluated, and a possible confirmation of the states seen in the invariant mass system of J/ψϕ by LHCb in B decays has been investigated.
