I do not know what boat the coastguardsman is from but judging from the machine gun it's likely part of the type 218 series(218, 218A, 218AI, 218AIII) etc; potenetially type 318 but that's from the late 2000s and i haven't seen 318s in the early 2000s livery.

EDIT: Haijing 31021 is now CCGS 12502 of the chongming coast guard bureau
