For more than 20 years China has used political and economic pressure on foreign companies and countries to prevent them designing and/or building new submarines for Taiwan. China is likely to be displeased with the Netherlands' company below unless China sees some offsetting benefit.
In a move involving considerable Dutch courage  the Netherlands' RH Marine company is to carry out some much needed electronics upgrades [probably including the combat system] to Taiwan's 2 Dutch built Chien Lung (aka Hai-Lung) class submarines.
Taiwan's Chinese-language Liberty Times commented ""This will also be helpful for the program to build home-grown submarines,”
In the same article the Taiwanese Navy aimed to reduce Chinese concerns. The Navy "stressed that the Dutch company’s participation in the upgrade program “is unrelated to [Taiwan's domestic submarine design and construction] program.”
On the RH Marine website. Perhaps this display could play a role in a submarine's combat system?
