Almost exactly one year to the day after launching an initial probe into India's solar energy policies, the U.S. yesterday officially followed through by filing a petition with the World Trade Organization challenging domestic content provisions within India's "Phase II" of its National Solar Mission (NSM). Technically, as a formal first step the U.S. has requested for the WTO to help find common ground with dispute settlement consultations; if no resolution happens within 60 days the U.S. may press for a formal WTO panel to settle the issue.
