A clever free-kick, practiced on the training ground, between De Bruyne and Wallace saw the Brazilian upended inside the box. The home players were upset, believing Wallace had dived.
But the referee had no hesitation and Lukaku coolly sent goalkeeper Kristsana Klanklin the wrong way to give Mourinho's side something to show for a controlled but unspectacular performance.
Only Ramires and De Bruyne kept their place in the team for the second-half with eight changes, including debutant Marco Van Ginkel.
Chelsea’s rhythm continued and Victor Moses’ direct running on the right-hand side caused problems for the Thai side.
Moses and De Bruyne tested Klanklin soon after the restart with the All-Stars' keeper producing a good doubl -save.
Seconds later, Hazard combined with Van Ginkel and the Belgian slammed his shot straight at the man between the sticks.
Yet at the other end, Chelsea were handed a scare in 66 minutes with All-Stars defender Kaimbi heading wide from yards out.
A worrying sign – but it was one of few in the game.
Van Ginkel was tidy in the second half, while De Bruyne impressed for 79 minutes and Wallace enjoyed a productive debut.
