Tips for companies sending employees overseas:
1. Do your homework, including risk assessment of the country and the business you are hoping to do there.
2. Prepare in-house plans that include "what-if" scenarios for various disasters and how to deal with them.
3. Run a test exercise in your company, and talk through possible options for dealing with contingencies.
4. Train all staff who will be travelling overseas, so they know how to behave if problems arise, whom to contact, and where to go.
5. Stay in contact with the travellers. Don't wait for a video of them in trouble to pop up on YouTube, or a frantic call from their family.
