New Delhi, May 14 :     President Boris Yeltsin has sent a special envoy to ensure that Indian foreign minister Jaswant Singh goes ahead with his May 24 visit to Moscow despite political upheaval in Russia that has seen the exit of Prime Minister Yevgeny Primakov and could yet lead to Yeltsin?s own ouster. Sergei Prikhodko, deputy head of the Russian President?s office, will arrive here tonight with a special message from Yeltsin seeking to firm up dates with Indian leaders about a summit-level meeting between the two countries. Prikhodko will call on Singh and foreign secretary K. Raghunath tomorrow to discuss the dates. If they are finalised then Prime Minister A.B. Vajpayee will have to pay a visit to Russian within the next few months. Officially, Delhi maintains that the visit of the Yeltsin?s special envoy is to discuss the Kosovo issue with Indian leaders. The foreign ministry spokesman said the two sides are likely to discuss several issues of bilateral importance, but the main focus will be on developments in the Balkans. But it was learnt that Prikhodko?s trip was decided only over the last few days, indicating that a major objective of his mission was to convince Singh to go ahead with his visit to Russia. As per arrangement, a summit-level meeting every year, alternately at the two capitals, will be held between the Russian President and the Indian Prime Minister. In March 1997, H.D. Deve Gowda had visited Moscow, when this arrangement was agreed upon. However, last year the summit could not be held since Yeltsin had to postpone his visit due to indifferent health. Earlier this year, Primakov as Russia?s Prime Minister, however, visited the country and held wide-ranging discussions with Vajpayee and other senior Indian leaders. A visit by the Indian Prime Minister is now expected. One of the compulsions of the Russian side to go ahead with the summit-level meeting with a ?caretaker? Prime Minister stems from the Kosovo developments. An isolated Moscow is desperately looking for friends like India to send out a strong signal to the Western military alliance. A visit by the Indian foreign minister followed in quick succession by a prime ministerial visit will perhaps do just that. Moscow had earlier this year proposed a trilateral axis between Russia, India and China. The proposal has been gaining ground since the Nato airstrikes began. During Raghunath?s visit to China for the joint working-group meeting last month, the Chinese leadership also hinted at a similar arrangement and sought Delhi?s cooperation in building up a multi-polar world order. India, along with Russia and China, has been critical of Nato?s ?unilateral? action in Yugoslavia and has been calling for an immediate cessation of hostilities. Nato?s Washington declaration, calling for ?flexibility? to include new members and justifying its decision to act in areas well beyond the boundaries of its members, has added to the worries in Delhi as well in Moscow.
