The Nasdaq Stock Market filed a proposed rule change with the Securities and Exchange Commission to set stricter initial listing standards for companies primarily operating in countries that restrict information access. This proposal was initially published for public comment in June 2020, and the SEC took various steps to consider its approval or disapproval. However, on February 1, 2021, Nasdaq withdrew the proposed rule change.
Simple Explanation
Nasdaq wanted to make it harder for companies from certain countries that don't share information easily to join their stock market, but they decided to cancel this plan for now.
