What due diligence protocols address the risk of "regulatory whiplash" in frontier markets prone to sudden policy reversals, such as India?

India’s 99% FDI plunge in 2025 highlights the danger of regulatory unpredictability—e.g., sudden tax追缴 for Samsung or forced supply chain overhauls for Amazon . Traditional due diligence focuses on current laws, but fails to anticipate "whiplash" reversals. How do investors build safeguards for this? Do they embed clauses in contracts that trigger exit rights if policy changes cost over 15% of projected profits, or partner with local legal firms to monitor draft legislation? I seek actionable due diligence steps specific to markets with a history of policy volatility, including how to quantify the financial impact of potential regulatory shifts before investing.
