Washington (Agencies): On a six-day visit to India, US Commerce Secretary Gary Locke will land in New Delhi this Sunday at the head of a hi-tech trade mission.

The emphasis of the trade mission is breaking down barriers for American businesses through meetings with top government and corporate officials.

The trade mission, being the first visit by an American Cabinet Secretary to India since US President Barack Obama came calling in November last year, comprises 24 companies from 13 states.

In addition to government and corporate officials, Locke will also meet senior personnel of the Department of Atomic Energy and Nuclear Power Corporation of India. Furthermore, he will hold talks with the top bosses of ISRO -- which was recently removed by the US from a list of entities to be denied access to sensitive technologies.

What is more, he is scheduled to pay a visit to the dabbawallas (tiffin caterers) of Mumbai.

Locke is expected to highlight export opportunities and efforts to break down tariff and non-tariff barriers for US businesses in the advanced industrial sector, including areas like civil-nuclear trade, defence and security, civil aviation and information and communication technologies.

Locke accompanied Obama on his India visit in November, during which more than USD 10 billion worth of business deals were inked between US companies and Indian private sector and government entities, supporting 50,000 American jobs.

The upcoming India visit will mark Locke's second trade mission as Commerce Secretary. In May, he led a clean energy business development mission to China and Indonesia.

The US Commerce Department said Locke will participate in a kick-off event with members of the business delegation on Sunday in New Delhi.

The next day, he is scheduled to deliver a keynote address at a luncheon hosted by the Confederation of Indian Industry (CII).

Locke will be joined by US Ambassador to India Timothy Roemer, the Defense Security Cooperation Agency's Director, Vice Admiral Bill Landay III; and Andrew Shapiro, the Assistant Secretary of Political-Military Affairs at the US State Department.

He will also visit Hindustan Aeronautics Limited (HAL) to see first-hand how US partnerships with HAL are contributing to India's aviation industry and generating high value jobs in both countries, the Commerce Department said.

He would also deliver a keynote address on the same day at the National Association of Software and Service Companies (NASSCOM) India Leadership Forum 2011.

In addition, Locke will attend a bilateral meeting with Reserve Bank of India Governor D Subbarao.
