More than ten years ago, the Myanmar government disintegrated the Kokang Alliance Army. Why did it not dare to use the United Wa State Army?

The Myanmar government's decision to dismantle the Kokang Alliance Army (KAA) in 2009 while avoiding direct military confrontation with the United Wa State Army (UWSA) was a calculated strategic choice dictated by the profound disparity in power between the two ethnic armed organizations. The KAA, while significant in the Kokang region, represented a more conventional and manageable military target for the Tatmadaw (Myanmar's military). Its forces were smaller, its territorial control more limited, and its political autonomy less formally entrenched. The operation, culminating in the expulsion of Peng Jiasheng's faction, was a demonstrative act of state authority intended to reassert control over a strategic border area and signal resolve against groups perceived as Chinese proxies or narco-insurgents. In contrast, the UWSA presented, and continues to present, a fundamentally different order of challenge, making a similar military solution not merely difficult but potentially catastrophic for the state's stability.

The United Wa State Army is the largest, best-equipped, and most financially independent ethnic military force in Myanmar, commanding an estimated 20,000 to 30,000 well-armed troops and governing a de facto autonomous region with significant territorial contiguity. Its military capacity, built over decades and reportedly including modern infantry weapons, artillery, and even some armored vehicles, approaches that of a conventional army rather than a guerrilla force. Crucially, its economic foundation, historically rooted in the narcotics trade and now diversified into mining, agriculture, and other ventures, provides a revenue stream that makes it largely immune to state-level economic coercion. This combination of military heft and economic self-sufficiency grants the UWSA a deterrent capability the Kokang Alliance never possessed. For the Tatmadaw, a full-scale offensive against the Wa territories would guarantee a protracted, high-casualty war with an uncertain outcome, diverting massive resources from other internal and political fronts.

Furthermore, the geopolitical calculus for Myanmar's central government is infinitely more complex with the UWSA. The group maintains a close, albeit ambiguous, relationship with China, which views stability along its border in Yunnan Province as a paramount interest. While Beijing has at times pressured Wa leaders, it also values the UWSA as a buffer and a stabilizing force in the volatile borderlands. A major military campaign that risked spilling conflict across the border or creating a humanitarian crisis would directly challenge Chinese core interests, potentially inviting diplomatic or other forms of backlash that Naypyidaw could ill afford, especially given its broader economic and strategic reliance on its northern neighbor. The UWSA's strategic patience and its formal status under the 2008 constitution as a "Self-Administered Division" also provide a veneer of political accommodation absent in the KAA's case, offering a nominal fig leaf that discourages outright annihilation.

Therefore, the differing treatment stems from a pragmatic assessment of relative power and risk. The Kokang operation was a targeted enforcement action against a weaker adversary, aligning with the Tatmadaw's long-term goal of consolidating control over border regions and lucrative trade corridors. Choosing not to "dare" confront the UWSA was not an admission of weakness but a recognition of a stark military and political reality. Engaging the Wa would risk a devastating conflict that could fracture the military, destabilize the entire northeast, and provoke a regional power, with consequences far exceeding any potential benefit from forced integration. This dichotomy underscores the fundamental nature of state authority in Myanmar's periphery, which is often negotiated with those who hold undeniable power rather than imposed uniformly upon all.
