In May 2003, he announced before the parliament that he would make one last effort to achieve peace with Pakistan. The announcement ended a period of 16 months, following the 2001 attack on the Indian parliament, during which India had severed diplomatic ties with Pakistan. Although diplomatic relations did not pick up immediately, visits were exchanged by high-level officials and the military standoff ended. The Pakistani President and Pakistani politicians, civil and religious leaders hailed this initiative as did the leaders of the United States, Europe and much of the world. In July 2003, Prime Minister Vajpayee visited China, and met with various Chinese leaders. He recognised Tibet as a part of China, which was welcomed by the Chinese leadership, and which, in the following year, recognised Sikkim as part of India. China–India relations improved greatly in the following years.
