Sorry to disappoint you, half of Chinese combat aircraft engine are domestic made. JH-7A turbofan is home made WS-9A. Z-10 gunship using WZ-9 turboshaft. Y-9 transport aircraft using WZ-6 turboshaft. Z-9 gunship and transport uses WZ-8 turboshaft.
J-11A series aircraft running on WS-10A engine. Even our J-7PG uses domestic WP-13 turbojet.
While India has non of domestic engine or turboshaft to talk about
