Is it sufficient to wash utensils, which have touched chicken, with soapy water
This question addresses whether or not soap kills "germs". The answer to your question has more to do with how pathogen free you really need to be. Firstly, knowledge about where your chicken comes from and how it was processed helps. Indeed, bleach or other kitchen approved sanitizers designed for commercial kitchen use are effective at eliminating bacteria.  The question is, to what degree do you really need to take this in your own kitchen?  I think personal comfort levels and needs vary for the home cook.  For me, cleaning hands, tools and surfaces with hot soapy water does the job.  I've never had a problem.  However, I could see instances where one might want to be even more careful.  For example, if a family member or guest had a compromised immune system one might want to play it extra safe.
