IANAL. International laws probably vary, but by having employees in a country, you may be subject to its laws.
For example, I am part owner of a Canadian company that sells an online service. If we hire US employees (developers), then we must collect sales tax and pay income tax for sales originating within the governing municipality.
Obviously, I am talking about US tax law, and your question is of a different nature, so the best thing to do is to contact a lawyer who has expertise in that area. I only offer my experience as evidence that the location of employees can impact the legal responsibilities of a foreign business.
