After coming to power, the PRC announced that its army would be occupying Tibet. India sent a letter of protest to China proposing negotiations on the Tibet issue. The newly formed PRC was more active in posting troops to the Aksai Chin border than the newly formed Indian republic was. India decided to take moves to ensure a stable Indo-Chinese border. In August 1950, China expressed its gratitude to India's attempts to "stabilize the Indo-Chinese border". To clear any doubts or ambiguities, Prime Minister Nehru stated in Parliament in 1950 that "Our maps show that the McMahon Line is our boundary and that is our boundary...we stand by that boundary and we will not let anyone else come across that boundary". China expressed no concerns at these statements.
