"An asset" here means a good thing or a positive quality. In this saying, it tells us that sensitivity could be seen by others as a positive quality/trait or a negative quality/trait depending on how the culture views it.
Another example: I would like for you to come and work for my company. Your experience will be an asset to our team.
