The 16-year-old Surrey sprinter pushed the pre-race favourite Alex Nelson, from Stoke, into second place.
"I'm going to be there and I'm going to win for Great Britain," he said. "Can you imagine it, running there in your home country with everyone backing you for victory. What more do I need to aim for?
"I plan on being there. This gives me an even bigger challenge in my career and there's much more to come from me. I will improve. This confirmed I'm a championship performer - I'm No 1."
It is still very early days for the likes of Aikines-Aryeetey - who won silver at last year's Junior Commonwealth Games - and Nelson, but the duo dominate the youth sprinting scene and, given the increased resources which will be available for 2012 Olympic preparations, their potential should blossom.
The qualifying rounds in Morocco suggested the final would produce a duel between the British pair, and so it transpired. Nelson, the world's fastest in his age group this year, had been identified as the likely winner of the blue riband event.
However, when it mattered most he succumbed to his rival, who showed he has the charisma and confidence to rise to the big occasion. Nelson said: "I gave it my everything. The better guy won on the day but what can you do? I'm totally shattered."
Aikines-Aryeetey, whose time of 10.35sec was a personal best, conceded: "In the beginning it was a struggle for me when racing against him and there were a lot of other good sprinters. So I've come a long way to beat that lot. I've learned to focus and learned, thanks to my coach, to prepare properly for every race.
"But I can't let this win get to me," added the world champion, who next week will compete at the European Junior Championships in Lithuania.
"I've just got to go there and concentrate and then go back home and play about. I might have a go at the 400m... long jump... anything to keep my eye in."
