In November 2011, following a meeting of its leaders, the NLD announced its intention to re-register as a political party to contend 48 by-elections necessitated by the promotion of parliamentarians to ministerial rank. Following the decision, Aung San Suu Kyi held a telephone conference with US President Barack Obama, in which it was agreed that Secretary of State Hillary Clinton would make a visit to Burma, a move received with caution by Burma's ally China. On 1 December 2011, Aung San Suu Kyi met with Hillary Clinton at the residence of the top-ranking US diplomat in Yangon.
