The Sweden international cancelled out Wesley Sneijder's opener in Beijing before Kevin-Prince Boateng netted what was to be the winning goal on 69 minutes, as the Serie A holders picked up their first trophy of the new campaign.
"We didn't play to our best in terms of quality, but both physically and mentally we were really strong, like we always are," he told Milan's official website.
"The playing side can be improved on, which is normal, after only a month's training it's difficult to play extremely well, but not playing well but being able to win is an important quality to have.
"Let's keep it this way, the team wants to win, I want to win, we are Milan and we are obliged to win because this is the club mentality. The history and tradition of the club impose this on us and this group is used to winning and the winning mentality is ingrained here, and we intend to continue this tradition.”
Ibrahimovic also took time to appreciate the contribution of his colleagues on the field and enthused: "We have started with a great victory. This is an important match for us and we are all delighted with the win.
"We have worked hard for a month – we can still do better – however, we are going home with the trophy. I am trying to do my best for the team. I am working hard to arrive where I want to arrive.
"It's thanks to my team-mates that I am doing so well, without them I would be nothing. I scored thanks to [Clarence] Seedorf, however the build up was perfect with everybody making the right movement and the ball was played right in front of the goal, what else could I do if not put it into the net?"
