Mousset, a graduate from the acclaimed Le Havre academy, signed a four-year deal at Vitality Stadium.
The 20-year-old became the club’s third summer signing and Howe believes the club have secured a real asset for both the short term and long term at the football club.
"There was a lot of competition for Lys’ services and it was quite a protected transfer so we are very pleased to have got it over the line," Howe told the Bournemouth Echo.
"Lys is a really talented young centre-forward who we believe will be a real asset for us, both in the short and long term.
"He has just had a really good season for Le Havre and scored a number of goals. Myself, Jason and our team of scouts have all watched him a lot and we all liked what we saw.
"He is an under-20 international and recently played in the Toulon Tournament where he performed very well for France.
"Last season was his breakthrough season when he did very well for them and showed he is a player of rich potential.
"He had a good grounding at Le Havre. They have produced some good players and Lys has all the makings of being another one.
"He has all the attributes you look for in a young player. He is a good size, he is very strong, very quick and knows where the goal is. He is very much in the AFC Bournemouth mould.
"We are really excited to have signed him and are very much looking forward to working with him."
Manager Eddie Howe also talked about the club's second signing Nathan Ake. See what he said about the Chelsea loanee here.
