Defense or cooperation between states and international investors in times of crisis?

International investment is protected by international law by setting the standards of legal treatment that host state governments have committed themselves to in their investment treaties. Therefore, these standards of protection must be respected even in times of crisis, regardless of the reason that generated it, the policy of attracting and maintaining an investment climate favorable to international investment being an attribute of each state. If he does not find adequate protection or if he cannot negotiate contracts adapted to these conditions, nothing can prevent an investor from changing the direction of his business, in order to protect the investment made. On the other side of the barricade, the states raise the shields of force majeure and necessity. Of course, it is preferable for the barricade to turn into a round table of cooperation. The issue of violating one or more standards by states is one of the most debated at the moment, as international arbitration practice has decisions that oblige states to significant compensation. In my study I used as a research method the interdependent introspection, analysis and synthesis through analogies developed in a comparative method.
