This project examines all WTO filings to determine if a private party could bring an action for damages arising under the same core of operative facts pursuant to a bilateral investment treaty. This article, Part I of the project, reviews all national treatment, most favored nation, quantitative restrictions, TBT, and SPS filings. After exploring the doctrinal and theoretical reasons for the trade/investment tension, it analyzes all trade filings under a model investment treaty applied in light of decided cases. The article classifies the filings into “Positive,” “Potentially Positive,” and “Negative” categories for trade and investment. The findings show a near perfect correlation between trade and investment.
