Indian business lobbyists said they are poised to enlist expatriate citizens in a global campaign to help save the troubled US-India nuclear accord.

A lobbying group with ties to the Confederation of Indian Industry plans to send as many as 100,000 e-mails next week to people of Indian origin living in countries ranging from Norway to New Zealand, according to a statement. The e-mail will urge recipients to tout the accord to politicians, newspapers and influential groups in their adopted homelands.

By lobbying in their home countries, "people of Indian origin can make a landmark contribution to India's energy security," the lobbying initiative, called the Nuclear Suppliers Group Campaign for India, said on its Web site. Energy-starved India would gain access to American nuclear power plant technology and fuel under the US-India accord.

The effort is aimed at swaying countries that belong to the Nuclear Suppliers Group, a 45-nation forum dedicated to limiting the spread of atomic weapons. The NSG would have to loosen its export controls to approve the accord, a step that requires the agreement of all members, including holdouts such as China, Austria, Sweden and Ireland.

Organizers of the campaign include Linda Spedding, a London-based lawyer who advises the New Delhi-based Council of Indian Industry, and Robinder Sachdev of New Delhi, who works for the US-India Political Action Committee. The PAC was active in successful efforts to persuade the US Congress to approve the nuclear accord.

The NSG is likely to take up the agreement later this year, provided the US and India can first resolve their differences over future Indian nuclear practices. Several NSG countries have privately expressed concerns about the accord, and if they could vote in a secret ballot, there is "no question most would oppose it," said Robert Einhorn, a former US Assistant secretary of state for nonproliferation.

NSG support for the agreement would represent a turnabout because the group started after India tested an atomic bomb in 1974 without having signed the Nuclear Non-Proliferation Treaty.
