The correct answer is Myanmar.
The South Asian Association for Regional Cooperation (SAARC) is a regional intergovernmental organization comprising eight member states in South Asia: Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka.
Myanmar is not a member of SAARC. It was invited to join the organization in 1997, but it has not yet acceded to the SAARC Charter. The main reason for Myanmar’s non-membership is its poor human rights record. The SAARC Charter requires all member states to respect the principles of democracy, human rights, and the rule of law. Myanmar’s government has been accused of widespread human rights abuses, including torture, arbitrary detention, and extrajudicial killings. The government has also been criticized for its suppression of democracy and its failure to hold free and fair elections.
In recent years, there have been some signs that Myanmar may be willing to join SAARC. In 2011, the government released several political prisoners and began to implement some democratic reforms. However, the government has not yet taken any concrete steps to join SAARC. It is unclear when or if Myanmar will become a member of the organization.
