Considering the amount of countries already buying Chinese weapons, this is highly unlikely, impractical and unfeasible.Egypt is deep in debt including to the IMF. It is highly unlikely they will buy non-Western aircraft. The FC-31 is also still not available for purchase on the wider market.
If China for whatever reason starts selling its aircraft worldwide it will also be hit with CAATSA sanctions similar to Russia. The US will threaten any countries buying Chinese weapons from access to international banking using SWIFT.
And high debt makes it more likely to buy Chinese which are mostly cheaper.
US has a specific law or foreign policy that restricts sale of equipment to potential adversaries of Israel that are superior to Israeli systems. Military advantage must always be in Israel's favor. Hence why American-origin equipment in middleast is always downgraded wrt Israel.Egypt has F-16/Rafale but the pain point is that they don’t have advanced medium range missiles to match. Maybe this is why they are looking at J-10C.
