Qatar, the largest supplier of liquefied natural gas (LNG) to India, has turned down a request from the latter to renegotiate long-term supply contracts. India demanded that the pricing mechanism for LNG imported from Qatar, linked to crude oil, needed to be revisited and long-term contracts renegotiated, based on a new mechanism. However, turning down such a request from India, Qatar has firmly underlined the “sanctity” of contracts already signed and said these cannot be renegotiated, although the Gulf nation was willing to commit additional LNG supplies at new prices.
