More recently - Thailand bought the improved and heavily modified 053-H3 designs (2XNaresuan class) with displacement of 3000 tons, this is definitely higher than our lead ship Bangabandhu class. These are (I'd posit) are very similar to the F22P designs acquired and fabricated in Pakistan. One thing to note is that engines, weapons and sensors (and placement choices in terms of superstructure) are of Western origin and vastly different in the case of these two countries.
