i'm not sure if that's an entirely accurate assessment... when
one thinks of western european sub makers, we generally think DCN
(French), Kockums (Swedish) and HDW (German).
but since 2000, Kockums and HDW underwent a series of consolidation
which ended up with the Swedish state-owned defence company Celsius
AB and another private German company (Preussag) taking joint
control over HDW and HDW acquiring a 100% stake in Kockums.
Sg is actually in a rather good position to acquire whichever sub
it wants since the RSN enjoys good working relations with both the
Swedish gov't, Kockums and DCN, which Sg has ordered frigates
from...
and needless to say, the Kockums-HDW merger was undertaken
primarily to share technology and gain a bigger share in the global
market for naval vessels.
This was in early 2000...

now here's a bombshell... guess what USA did to keep its half of
the bargain to supply Taiwan with subs...
Australian Defence Magazine, May 2002
US merchant bank One Equity Partners (OEP) has bought a controlling
interest in German submarine builder HDW. The bank, which is owned
by Chicago-based Bank One (formerly First Chicago) has acquired 75
per cent of the firm from its German shareholders Preussag, Babcock
Borsig and Bayern Finanz. Babcock Borsig retains a 25 per cant
stake in HDW.

so now, one of the more prominent European naval supplier, is
American owned... and since M'sia has introduced advanced submarine
capabilities to the region, the door is WIDE open for Sg to
purchase whatever diesel sub it bloody wants... the Germans have
never been part of the equation but i seriously did not think that
they would prove uncooperative should we have decided to deal with
them.
true, America has export restrictions too, but Sg has dealt with
them before and like i said: Sg is not introducing a new capability
into the region.
so i do not foresee serious problems if Sg decides to buy a Swedish
designed sub equipped with top of the line Swedish and German
technology from big brother America and build it in Singapore with
full technology transfer 
pure speculation on my part... please correct my humble opinion
should my reasoning prove flawed...
