The Ligue 1 champions were always in command in a one-sided affair at the Workers Stadium in Beijing, dispatching the Coupe de France winners with little difficulty.
Once again it was Zlatan Ibrahimovic that was the star for Laurent Blanc's men, as the 32-year-old fired home a first-half double in another glowing exhibition of his talents in front of goal.
Guingamp spurned a chance to get back into the game in the 32nd minute with Mustapha Yatabare's penalty miss.
And the underdogs were left to rue that wasted opportunity as PSG comfortably saw out the game to add yet another trophy to their collection following consecutive league triumphs and last season's Coupe de la Ligue success.
PSG did all of the early pressing and needed just nine minutes to break the deadlock, Ibrahimovic finding the net in typically spectacular fashion.
But Jocelyn Gourvennec's men were offered a lifeline on the half-hour mark as PSG centre-back Marquinhos conceded a penalty, referee Clement Turpin adjudging the Brazilian to have illegally blocked off Claudio Beauvue.
However, Yatabare - Guingamp's top scorer last season - could not keep his composure as his poor spot-kick was well saved by Salvatore Sirigu.
The second half was bereft of goalmouth action in comparison to the first, although PSG teenager Hervin Ongenda did fire wide five minutes after the interval.
Blanc's side took their foot off the gas somewhat in stifling conditions, but substitute Edinson Cavani should have made it three when he blazed over the crossbar following a superb through ball from Pastore.
But despite Cavani's profligacy, Guingamp were unable to mount a comeback as the gulf in class proved too much.
