Finding that although the law's substantive rules do accommodate the structural problems SMEs face when investing abroad, under the lex lata, they are still often prevented from accessing investment arbitration due to their limited resources. By considering current reform efforts, the volume develops practicable approaches to overcome this shortcoming.
