NEW DELHI (AFP) - Myanmars military ruler Than Shwe arrives in India for a state visit that underscores the growing strategic ties between the worlds largest democracy and one of its most repressive regimes. The red-carpet reception planned for Shwe, who rarely travels abroad, has been sharply criticised by human rights groups as a betrayal of Indias democratic credentials and an implicit endorsement of Shwes junta. Shwe will hold talks with Prime Minister Manmohan Singh on economic and military co-operation and a series of trade deals are expected to be signed during the five-day visit. Once a staunch supporter of Myanmars democracy icon Aung San Suu Kyi, India began engaging the junta in the mid-1990s as security, energy and strategic priorities began to override concerns over democracy and human rights. As well as needing the juntas help to counter ethnic separatists operating along their remote common border, India is eyeing oil and gas fields in Myanmar and fears losing out to China in the race for strategic space in Asia. India and Myanmar will work towards expanding engagements at all levels, an India foreign ministry official said of Shwes visit. It is crucial for India to cement its relationship with Myanmar to deal with the insurgency that plagues the northeast and to counter balance Chinas influence, the official told AFP on condition of anonymity. The European Union, United States and other countries have targeted Myanmar with economic sanctions and travel bans, but their impact on the military regime has been diluted by support from China, India and Thailand. The junta, which has ruled with an iron fist for nearly 50 years, has promised to hold Myanmars first elections since 1990 later this year. Western nations have dismissed the proposed poll as a sham, and Aung San Suu Kyis National League for Democracy is boycotting the ballot because of laws which would have forced it to expel her and other members in prison before it could participate. Keen to obtain international legitimacy for the vote, Shwe is expected to seek Indias endorsement of the poll during his visit. A senior Indian foreign ministry official said India would stress the need for the ballot to be free and fair. We will also offer our assistance in conducting the elections, the official said. On Wednesday, The International Federation for Human Rights, which represents 164 organisations across the world, wrote to Singh raising its concerns about his meeting with Shwe. The long list of the juntas well-documented human rights abuses includes acts that may amount to war crimes and crimes against humanity under international law, the letter said. Maintaining relations with Myanmars military leaders without due regard to universal human rights is unbecoming of the worlds largest democracy and a responsible world power, it added. Some Indian analysts defend what they see as New Delhis pragmatic approach that is dictated by national interest rather than moral considerations. Engagement is not an endorsement, said C. Uday Bhaskar, director of National Maritime Foundation in New Delhi. India is eager to boost its investment in gas and hydroelectricity projects in Myanmar and earlier this year its largest vehicle manufacturer, Tata Motors, agreed a deal to establish a heavy truck plant in Myanmar. Economics is the key driving point and India does not enjoy the luxury to only deal with regimes with the same political, social values, Bhaskar said. However, critics of Myanmars military regime say Indias strategy is ill-conceived and damaging to its international profile. India is basically hooking up with one of the worlds most brutal dictatorships, said Benedict Rogers, author of Than Shwe: Unmasking Burmas Tyrant. India will not benefit in the way it hopes. And it could risk losing out in terms of its reputation on the world stage, Rogers, who works for the human rights organisation Christian Solidarity Worldwide, told AFP.
