Hi Markus,
far from being an expert by comparing the bow of the newbuilt she might be a Type 053H frigates like in these:

Hi Manfred, thanks for your comment. Usally I do not photographing Navy ships and so on i'm not familiar with them.

Hi Markus,
as the newbuilt seems to be moored to 131 inboard we might look at Zhonghua Shipyard, Shanghai in 1973.
131 would be NANJING 131, a type 051 destroyer for the China East Sea Fleet completed in 1973.
The unnamed might be a sister? Looks a bit smaller?
Just a thought,
Best wishes, Manfred
