Question: What major conflict is the country between the country that hosted the tournament and the country where That Dam is from known for?

Knowledge 1: That Dam
That Dam (Lao ທາດດຳ, meaning Black Stupa) is a large stupa located in Vientiane, Laos. Many Laotians believe it is inhabited by a seven-headed nāga who tried to protect them from an invasion by the Siamese army in 1827. [SEP] Knowledge 2: Geography of Myanmar
Myanmar (also known as Burma) is the northwestern-most country of mainland Southeast Asia, bordering China, India, Bangladesh, Thailand and Laos. It lies along the Indian and Eurasian Plates, to the southeast of the Himalayas. To its west is the Bay of Bengal and to its south is the Andaman Sea. It is strategically located near major Indian Ocean shipping lanes. [SEP] Knowledge 3: Myanmar
For most of its independent years, the country has been engrossed in rampant ethnic strife and Burma's myriad ethnic groups have been involved in one of the world's longest-running ongoing civil wars. During this time, the United Nations and several other organisations have reported consistent and systematic human rights violations in the country. In 2011, the military junta was officially dissolved following a 2010 general election, and a nominally civilian government was installed. While former military leaders still wield enormous power in the country, Burmese Military have taken steps toward relinquishing control of the government. This, along with the release of Aung San Suu Kyi and political prisoners, has improved the country's human rights record and foreign relations, and has led to the easing of trade and other economic sanctions. There is, however, continuing criticism of the government's treatment of the Muslim Rohingya minority and its poor response to the religious clashes. In the landmark 2015 election, Aung San Suu Kyi's party won a majority in both houses, ending military rule. [SEP] Knowledge 4: 2020 AFC U-23 Championship qualification
