"I offered to launch a Korean satellite on an Indian space launch vehicle," Prime Minister Manmohan Singh said at a joint press briefing with South Korean President Lee Myung-Bak after bilateral talks.
The two leaders expressed happiness over the increase in bilateral trade following the signing of the Comprehensive Economic Partnership Agreement last year and set a target of achieving USD 40 billion trade by 2015.
Singh also invited South Korean companies to invest in a big way in the infrastructure sector in India.
The two sides also signed an agreement on simplifying visa procedures for the business community.
Singh also sought Seoul's support for India's effort to be a member of the Nuclear Suppliers Group, the Australia Group and the Wassenaar Arrangement
Singh said India has also decided to post a defence attache at its embassy in Seoul.
The move comes in the wake of South Korea's desire to enhance defence cooperation with India.
Ahead of his talks with President Lee, Singh laid a wreath at the Memorial Tower at the National Cemetery.
Singh arrived in Seoul on Saturday for a four-day visit to attend a Nuclear Security Summit. The two-day summit begins on Monday, when world leaders will meet over dinner.
Tuesday would see packed sessions on the theme 'Beyond Security Towards Peace' where Singh is expected to unveil steps conceived by India to tackle the challenges of nuclear terrorism.
