''Yes'' State Department Spokesman P J Crowley told reporters when asked if US considers Bhopal gas tragedy as a closed case now.
Later the State Department Department official clarified that legally Bhopal gas case is closed.
In December 1984, a Union Carbide plant in Bhopal spewed toxic gas into surrounding neighbourhoods, killing thousands instantly and tens of thousands later.
In 1999, Dow Chemical Company bought the Union Carbide which was responsible for the world's worst industrial disaster in 1984 - the Bhopal gas tragedy.
This year, a court sentenced seven Indian managers to two-year jail terms.
After public outrage that the sentences were not tougher, India promised to renew efforts to extradite Union Carbide's former boss Warren Anderson.
Meanwhile, BJP and Left parties today alleged that the US was trying to armtwist India to let Dow Chemicals go scotfree with regard to its liability in the Bhopal gas tragedy.
"We have interacted with the Indian government on the Bhopal issue. On an ongoing basis going back many years, we've expressed our sympathy and concern about the impact that this had on the people of India," Crowley said.
The State Department official, however, refrained from making comment on the content of he email exchanged between between Montek Singh Ahluwalia, Deputy Chairman of the Planning Commission and Mike Froman, the US Deputy National Security Advisor of India and the US.
Crowley said it is not correct to establish link between two different issues.
"Actually, we don't normally comment about internal e-mails. However, I believe the Indian official involved in that e-mail exchange has himself indicated that the subject of the e-mail was an upcoming issue of importance to India and that there was no connection to any other issue. But this exchange, the link that was suggested is not there," Crowley said.
