Luiten carded a closing 71 to finish 17 under par at Diamond Country Club, two shots ahead of Bjorn, who birdied the 18th for a 68 to claim outright second ahead of China's Liang Wenchong (66) and France's Romain Wattel (69).
"You have to take your hat off to Joost and he deserves it more than anyone," Bjorn told European Tour Radio. "I played with him last week on Sunday (in Sweden) and you see there is a player that has got everything to become a world-class player.
"He has been there or thereabouts so many times and now he finally gets that win and it will kick him on to greater things. He carried himself well even when you thought he was going to win and he didn't. He kept going and got his payday and that's good for him."
Luiten began the final day with a three-shot lead but saw that instantly reduced to one when he three-putted the opening hole and playing partner Jorge Campillo made birdie.
Birdies on the second and seventh ensured the gap was back to three shots by the turn and Luiten looked like having more breathing space when Wattel three-putted the 12th, only to make exactly the same mistake himself on the 11th. With Liang making a birdie on the 15th and Bjorn picking up shots on the 10th and 12th, they were now just two shots back.
Play was suspended due to the threat of lightning in the area with Luiten on the 14th tee, but he showed no ill effects when it resumed an hour later and struck the decisive blow on the 16th, where his approach almost span back into the hole and set up an easy birdie.
"It's been a great week so I am really, really happy," Luiten told Sky Sports 3. "It was a long day, I started off with a bogey but I hit the ball nicely so I just wanted to focus on that, hit the greens, two putt and make the others chase me.
"Unfortunately I made a few mistakes on the greens and didn't make a lot of putts, but in the end I was three clear after my birdie on 16 and that gave me a little bit of air. It's always nice to finish par, par and hold the trophy."
