Rumor has it.

For whatever the reason, the PLAN does not like to place its imported warships under international spotlight and they seldom take part in foreign port calls.

After a three year pause, two more newly constructed Type022 FAC spotted in Guangxi. It might be too early to tell, but rumor has it the Type 022 Houbei construction program has been restarted.
