At least 1 Su-30 MKI, has been produced by HAL from its facility at Nasik in 2004 or 2005. All the fabrication, assembly and testing was done in various parts of India.
I'm afraid it is me who is not following you. Manufacturing (or "produced" as mentioned by you) is not equivalent to assembling from kits.
The manufacturing line of the MKI jets shall not be decommissioned, according to the latest news report that was posted by me. Since indigenous assembly is now more expensive, it has been decided that presently some components and systems shall be sourced from Russia. This shall lead to reduction in costs of assembly.
