In 2003, China acknowledged Sikkim as a part of India while India recognized Tibet as part of China. The Dalai Lama has often asserted that Tibet should be given meaningful autonomy within China, not independence. In 2005, the King of Nepal imposed direct rule, which led to the monarchy's overthrow, the end of the civil war, and the creation of the Federal Democratic Republic of Nepal in 2008. Bhutan held its first general election in 2008. In 2011, India granted duty-free access to most Bangladeshi products. In 2012, India affirmed in principle to allow Bangladesh, Bhutan, and Nepal to transit its territory for trade movement. In 2014, Bangladesh and India resolved their maritime boundary dispute at a UN tribunal. In 2015, India and Bangladesh signed a land boundary agreement to resolve border disputes. In 2014 Bangladesh and Bhutan signed a trade agreement in which Bhutan gained duty-free access for 90products in the Bangladeshi market.
