The strange vector form factors are evaluated in the range between Q²=0 and Q²=1GeV² in the framework of the SU(3) chiral quark-soliton model (or semi-bosonized SU(3) Nambu-Jona-Lasinio model). The rotational 1/Nc and mₛ corrections are taken into account up to linear order. Taking care of a proper Yukawa-tail of the kaonic cloud, we get r² Sachsₛ=-0.095 fm² and μₛ = -0.68μₙ. The results are compared with several different models.
