We have proceeded in this way in the past, by including in our legislation the two-year period prescribed by the WTO rules.
I think the intention is to confirm the temporary nature of that change. A two-year period is long enough to analyze the situation and decide whether it is necessary to impose safeguards. I think that, if the period was shorter, the 200-day time frame would expire and the tribunal may lack time to finish its process. The selected period gives us enough time to decide whether or not to impose measures.
There is nothing scientific about it. The intention is to confirm that the change is temporary and that we will afterwards go back to applying the law as it was.
