We generalize the strong Hanani–Tutte theorem to clustered graphs with two disjoint clus-ters, and show that an extension of our result to flat clustered graphs with three disjoint clusters is not possible. Moreover, show a variant of Hanani–Tutte theorem for c-connected clustered graphs. We also give a new and short proof for a result by Di Battista and Frati about efficient c-planarity testing of an embedded flat clustered graph with small faces. Our proof is based on the matroid intersection algorithm.
