I think that this like the phanto lord arc of fairy tail. Sangi's rich and powerful family paid off big mom or someone insainly strong like an admiral or Sakazuki to attck the strawhats unless sanji cooperates. And judging by his reactions it's someone he knows this is someone who will kill his crew, or at least nami and robin knowing sanji.
