I don't see how Europe owning Egypt would transfer technology.
If anything it'd make contact with the east more unstable and weaken technology transfer.
To better do that...
Well maybe no Islam-thus a Persia which remains strong and grows providing a direct bridge between Christendom and China (assuming it also gains friendly terms with Rome...)
But if you really must have it that late...Getting rid of the crusades and better European relations with Islam would be needed.
Anyway.
I'd agree Chinese weapons weren't suited for Europe.
The repeating crossbow for example; excellent engineering but not very good vs. armour.
