The United Wa State Army and its ally the National Democratic Alliance Army (NDAA) also called Mongla, were informed by the Burma Army yesterday, 28 April, to depart from their bases outside designated territories by tomorrow, 30 April, quoting informed sources from the Sino-Burma border, Shan Herald Agency for News (S.H.A.N.) said.
The messages were by phone calls by separate regional commands: The order to UWSA in Panghsang was from commanding officer of the Northeastern Region Command (Lashio), while the order to Mongla was from the commander of the Triangle Region Command (Kengtung). According to a source close to the Mongla leadership, the Burma Army would attack Wa and Mongla posts at anytime they wanted if the ethnic troops failed to withdraw their bases by the given time limit.
The United Wa State Army (UWSA) has reportedly ordered all of its frontline units on 24-hour alert along the Salween river, a shared border with its ally the Shan State Army (SSA) ‘North’. The UWSA have alerted all of its troops to be ready to defend Wa State, although they do not want war. They will not fire the first shot, said a senior Wa officer.

SSA ‘North’ has been combating Burmese armed forces currently since the junta issued the ultimatum to accept the Border Guard Force program. Shan State Army (SSA) ‘North’ has been fighting with the Burmese Army since 13 March. It was given an ultimatum to surrender by the end of March and to pull out from all their bases deploying in areas outside its main base. The latest skirmishes between the two apparently took place twice in Kehsi Township.
The Burmese Army has had at least 30 killed and 100 wounded, while the SSA has had four killed and eight wounded, according to SSA sources.
According to the latest information, Shan State Army (SSA)-North’s core base Namlao in Tangyan township, the gateway to its ally the United Wa State Army (UWSA), was seized by the Burma Army on 15 March after heavy fighting between the two sides for almost half a day, according to sources from the SSA.
The Burma Army allegedly accused them of breaching their 1989 agreement that they would not make recruitment or expand their territories. Currently, the UWSA leaders are still holding an emergency meeting to discuss the ultimatum.
In the meantime, the NDAA has already pulled out from two of its tactical bases in Wan Kho and Pong Hiet in Shan State East’s Mong-yawng township by the side of the west bank  of the Mekong. Wan Kho base was taken by the Burma Army on 27 April. And NDAA troops in Pong Hiet were reported to have pulled out yesterday, Shan Heral Agency for News said.
According to a Burma Army backed militia source, the Burma armed forces came with the strength of 100 soldiers and enclosed the group in the morning without firing a shot. After the NDAA troops left the area in the evening, Burmese soldiers from the Light Infantry Battalion (LIB) 573 based in Mongphyak took over the post.
In March 2010, Chinese defense officials made an effort to repair the worsening relationship between the UWSA and the ruling military junta which demanded repeatedly the Wa accept its Border Guard Force plan. Despite the fact that details are lacking, sources say China is making another attempt to convince the Burmese junta of the futility of war against the UWSA.
Recently, two of the anti-Border Guard Force groups – United Wa State Army (UWSA) and National Democratic Alliance Army (NDAA) – were reportedly advised by China not to join in with any groups opposing the military junta. If not they would be under attacks similar to the Kachin Independence Army (KIA) and Shan State Army (SSA) North, according to a Sino-Burma border source.
Chinese officials suggested that unless (UWSA) and (NDAA) get involved with the new ethnic alliance, the military junta will leave the two alone, a source said.  The report has to be confirmed by Wa or Mongla authorities yet. Even if correct, it might be also a ploy by the junta. The junta doesn’t have the strength to make an offensive towards several ethnic groups at the same time, observers believe.
At present, the military junta has spread out more troops along the Salween River to break off a possible relationships between the UWSA and SSA ‘North’. The SSA is active in the west of the Salween while the UWSA is in the east.
