West Bengal must do away with the regulatory pricing mechanism in the power sector and allow market forces to determine tariff, the US assistant secretary of commerce for market access and compliance, David Bohigian, said here on Monday.

Bohigian met state commerce and industries secretary Sabyasachi Sen and discussed at length the changes required in the state?s policies to make it more attractive for foreign investors. He also met dignitaries from the US embassy in New Delhi and the consulate in Kolkata.

?Investors prefer certainty in the political environment. There are a lot of opportunities in West Bengal, but a risk-reward assessment has to be done,? said Bohigian during a press conference at the Energy Education Park.

When asked whether frequent visits from high-raqnking US officials had something to do with the stiff resistance that the Left Front was putting up to the Indo-US nuclear deal, Bohigian said: ?It?s a reflection of the opportunities in the state.?
