NEW DELHI (Reuters) - US Secretary of State Hillary Clinton urged India on Friday to join Washington in supporting Pakistans fight against terrorism. She arrived in India Friday for a three-day visit aimed at deepening strategic ties with a country viewed as a global player on trade, arms control and climate change. Her first stop in Mumbai includes meetings with key business leaders, educational professionals and a womens group and will see her pay tribute to the 166 people who died in last years strikes on the city. Hillary is due to arrive in Mumbai late on Friday to start a five-day visit designed to cement ties and dispel any doubts about US President Barack Obamas commitment to Indias role as a rising global power. Hillary Clinton, in an opinion piece published in the Times of India newspaper on Friday, wrote that both India and the US had experienced searing terrorist attacks. We both seek a more secure world for our citizens. We should intensify our defence and law enforcement cooperation to that end. And we should encourage Pakistan as that nation confronts the challenge of violent extremism, she wrote. Monitoring Desk adds: The US has not pressurised India to return to the dialogue table with Pakistan, said Secretary of State Hillary Clinton and added that she was 'very impressed with Indian Prime Minister Manmohan Singhs discussion with his Pakistani counterpart Yousuf Raza Gilani in Egypt. No, not at all, said Clinton in an interview to CNN-IBN while replying to a question on whether it was the US which was pressurising India to return to the dialogue table. I am impressed with Prime Minister Singh meeting both President Asif Zardari and now with Prime Minister Gilani. This dialogue between India and Pakistan is certainly one that could only be pursued with the agreement and commitment of the two countries and the leaders, but of course United States is very supportive with steps that India might take towards any agreement that India and Pakistan might reach, she said. Clinton said In fact, I think in the last few days there has been real commitment that was discussed between Gilani and Singh about the commitment of the Pakistan government to pursuing the Mumbai attackers and their associated organisations who provide the training and the employment of terrorists. She also reiterated the Obama administrations commitment to the Indo-US civil nuclear agreement but said she would like to discuss with Indian leaders the ways to prevent the proliferation of nuclear material and weapons to state and non-state actors that pose a threat to India, to the US and to the many countries around the world. Expressing the US concern about proliferation, she said the Obama administration is, as are other G-8 members, very concerned about proliferation. The US is very committed to our nuclear agreement with India, but I want to hear from the Indian leaders what they believe would be the useful step that we could mutually pursue that would avoid the concern that I think we share about such material falling into the wrong hands, she said. Trying to dispel the perception that US was not doing enough to put pressure on Pakistan to bring to book those responsible for 26/11 attacks, she said We have engaged in very important ongoing discussion with the Pakistani forces, civilian government as well as the military about the importance of standing up against extremists no matter who they are and where they might strike. APP adds: The United States on Thursday said it was encouraged by positive signals emanating from Pakistani and Indian leaders decision on resumption of dialogue. Of course, were very encouraged by these positive signals coming out of the talks, State Department spokesman Ian Kelly said, commenting on the outcome of a meeting between Prime Minister Yousuf Raza Gilani and his Indian counterpart Manmohan Singh in Egyptian resort of Sherm el Sheikh on Thursday. Kelly did not offer detailed comment on the development but remarked that the initial indications are that this is something very positive. The leaders of the two South Asian nations, meeting on the sidelines of a Non-Aligned Movement Summit, decided to de-link composite dialogue from terrorism, and recognised that dialogue was the only way forward.
