In the context of international economic integration, along with measures to ensure that foreign investors are not forced to nationalize property and are not discriminated against, Argentina has made many preferential commitments on transfer. Foreign currency exchange and tax incentives. However, during the financial crisis of the 2000s, Argentina could not keep its promise. Instead, Argentina changes its policy of adjusting taxes and floating exchange rates. The change in this investment policy, directly or indirectly, has affected the legitimate interests and expectations of thousands of foreign investors in Argentina. Therefore a series of international investment lawsuits have been submitted to ICSID. As a result, many arbitral tribunals concluded that Argentina compensated billions of dollars to foreign investors. In fact, Argentina has applied many different measures to delay the execution of ICSID arbitration decision for many years.
