Arsenal are thought to be weighing up a summer swoop for Williams, while Liverpool have been long-term admirers of the talented central defender.
Williams has been one of Swansea's star performers this season and he has established himself as one of the best centre-backs in the Premier League over the last 18 months.
Laudrup believes the transfer speculation is a compliment to how well Williams has done for Swansea.
"When there are rumours about these clubs wanting someone from here it is because the player has done well - and Ashley has," Laudrup told the Daily Mirror.
"What else can I do? I can't call Arsenal and say 'Is it true?' - and I don't think Arsene Wenger would answer anyway, he has other things to think about. It is just part of the game.
"We will have to cope with these stories and remember it means people have seen what we have done here and what the players have done.
"He and Chico [Flores, his fellow centre-half] have been a great pair. They are doing great together and I will be unhappy to lose that pairing for next season."
Laudrup believes the fact that Williams penned a new long-term deal to keep him at Swansea until 2015 last year indicates the defender is committed to the club.
He told Sky Sports: "Ashley renewed his contract a few months ago so if he did that I imagine it's because he wants to stay here next year. Otherwise, why renew your contract?
"If you renew your contract I don't think it's because you want to leave next season."
