Langit Nusantara and the Strategic Gamble in the Indo-Pacific

The controversy surrounding blanket overflight clearance serves as a reminder that in modern geopolitics, seemingly empty spaces often become the most contested domains.

Jakarta (ANTARA) - The Indonesian government has officially denied the existence of a blanket overflight clearance agreement for the United States, and this denial constitutes a crucial diplomatic step.

However, the denial has not immediately quelled regional anxieties and speculation. The issue of blanket overflight clearance, which is intrinsically linked to air sovereignty, resonates far beyond the bounds of bureaucratic technicalities.

For some countries in the region, this issue is not merely about the veracity of an agreement, but rather how perceptions of Indonesia’s strategic policy direction are being interpreted.

Through a press conference held on Friday (17/4), China, via its Foreign Ministry spokesperson Guo Jiakun, responded to the blanket overflight clearance issue and connected it to the ASEAN Charter and the Treaty of Amity and Cooperation in Southeast Asia (TAC).

Jiakun emphasised that the ASEAN Charter and the Treaty of Amity and Cooperation in Southeast Asia (TAC) stipulate that member states must act in accordance with the principle of collective responsibility in enhancing regional peace, security, and prosperity, and to refrain from any participation, including the use of territory, that threatens the sovereignty or territorial integrity of ASEAN members.

China’s response is undoubtedly tied to the escalating rivalry between the United States and China in the Indo-Pacific region. In this context, any potential military access, including air transit permissions, becomes part of a broader strategic calculus.

Countries in the region, including China, may tend to interpret Indonesia’s actions not only from its official statements but also from the consistency of practices on the ground.

This can be understood. After all, in an increasingly fluid geopolitical landscape, even the absence of policy can be interpreted as a signal. Especially when it concerns airspace, a domain inherently related to sovereignty, security, and power projection.

Indonesia has long positioned itself as an active non-aligned country, seeking to maintain balance amid the pulls of two major powers.

However, in reality, this position is becoming increasingly difficult to sustain simply when regional dynamics demand clearer and more firm stances. In some cases, a non-aligned posture is still perceived as a form of covert alignment by certain parties.

The blanket overflight clearance issue also opens up discussion on the boundaries between legitimate military cooperation and the potential erosion of sovereignty.

In international law, the principle of state sovereignty over airspace – as affirmed in the 1944 Chicago Convention – is fundamental.

However, since regulations for military aircraft do not fully fall under the International Civil Aviation Organization (ICAO), practices on the ground often depend on bilateral agreements and diplomatic permissions, which in certain conditions allow for varying interpretations among countries.
