With relations in a parlous state between Colombia and Venezuela, Colombia is considering upgrading their navy:
Colombia is negotiating with Germany to buy up to six recently retired Type 206A coastal submarines. The 206As are meant to be an inexpensive counter to new Russian Kilo subs being purchased by neighboring Venezuela. Colombia still has two older (1,200 ton) Type 209 subs and nine miniature subs. All are over three decades old, and so are the Type 206As. But the 206As have been better cared for and were updated in the 1990s. Colombia already has sailors with lots of experience on German submarines and the Type 206s can be obtained cheap. Exactly how cheap is currently under negotiation.
[. . .] If there were a war with Venezuela (which has been acting very belligerent over the last few years), the Type 206s would be used to shut down Venezuelan ports and destroy oil facilities. Venezuela also has two 1970s era Type 209 subs, said to be in worse shape than their Colombian counterparts.

Wikipedia says of these submarines:
The Type 206 is a class of diesel-electric submarines (U-boats) developed by Howaldtswerke-Deutsche Werft (HDW). Its design is based on the preceding Type 205 submarine class. These small and agile submarines were built during the Cold War to operate in the shallow Baltic Sea and attack Warsaw Pact shipping if the war turned hot. The pressure hulls were built out of non-magnetic steel to counter the threat of magnetic naval mines and make detection with MAD sensors more difficult. The low emission profile allowed the submarines in exercises to intrude even into well protected opposing forces such as carrier formations with their screen.

A major mid-life modernisation was conducted on twelve of these submarines, the boats concerned now being officially designated Type 206A. The work started in mid-1987 and completed in February 1992, being carried out by Nordseewerke, Emden; this upgrade includes:
The STN Atlas DBQS-21D sonar has been fitted, together with new periscopes, and a new weapon control system (LEWA). The ESM system has been replaced and GPS navigation installed. The rebuilt submarines are armed with new torpedoes (Seeaal), and the propulsion system has been comprehensively refurbished, and improvements have been made to the accommodation.
