The Villa chairman stressed that "splashing" money does not always yield success.
Villa struggled for goals last season, with top scorer Jordan Ayew netting just seven times in the Premier League as they slumped to relegation in miserable fashion.
New manager Roberto Di Matteo has already signed a goalkeeper, defender, and a central midfielder this summer, but there appears to be a pressing need to bring in a forward.
It was reported on Wednesday that Villa had made an offer for Bristol City's 20-goal striker Jonathan Kodjia, but it has since been claimed that offer - allegedly around £5 million - has been rejected.
Xia has been prominent in interacting with supporters on Twitter, stressing last week that fans should have patience over the club's transfer activity.
He has now spoken up on the issue of the search for a striker, insisting that the club have a strategy which involves more than just throwing money around.
We all know that and believe we have the best strategy and plan. https://t.co/mTCRWUQHJq— Dr. Tony Xia (@Dr_TonyXia) July 21, 2016

Responding to a fan's message that the club need "a decent striker", Xia wroteL "We all know that and believe we have the best strategy and plan."
Moments before, he had tweeted: "We have learnt from experience that splashing money and adding players cannot guarantee the success. Please trust RDM [Di Matteo] and teams know what they need [to] do!"
Villa do have a prolific Championship goalscorer in their squad in the form of Rudy Gestede, with the striker having hit 34 goals in 66 appearances as a permanent player for Blackburn Rovers prior to his move to Villa Park.
However, with Ayew's future uncertain and Gabby Agbonlahor and Libor Kozak struggling for form and fitness over the last few years, another attacking option would be a welcome addition for the Championship club.
