US Ambassador Timothy J. Roemer on Friday laid emphasis on strong relations between India and China for a peaceful south-east Asia. He was speaking to reporters in New Delhi today. Not giving any direct reply on a question on China's building nuclear reactors in Pakistan, he accepted that Pakistan is not trust worthy in the field of nuclear proliferation seeing its past record. Talking about strong links between India and the US, especially following the civil nuclear deal, Roemer said that India and US are seeing the world from the same prism and it is a very exciting time for the US president to visit India.
