boundaries (Fawcett & Hurrell, 1995; Söderbaum & Shaw, 2003; Katzenstein, 2005). For
example, Acharya (2012) referred to regionalism as a “global heritage” with diverse
trajectories in different regions of the world, transcending Eurocentric models (Acharya,
2012, p. 3; Söderbaum, 2015). This pluralistic understanding of regionalism and the
rapid proliferation of regional organisations have also paved the way for overlapping
regionalism discussions (Panke & Stapel, 2018; Reinsberg & Westerwinter, 2023).
The expansion of global and regional organisations has not been strictly progressive or
singularly focused. This has led to overlapping memberships, mandates, functions, and
boundaries, which are described as overlapping regionalism (Panke & Stapel, 2018). This
is closely related to the complexity of governmental systems where multiple institutions
with similar objectives exist, resulting in redundant abundance and functional rivalry
(Reinsberg & Westerwinter, 2023). As stated by Panke and Stapel (2018, p. 239),
overlapping regional organisations occur when states join more than one organisation
under a similar mandate or enforcement that provides both opportunities and constraints
for states. This gives states the opportunity to use multifaceted strategies to strengthen
and protect their interests, primarily when centralised global institutions such as the UN
or WTO are in political deadlocks or unresponsive. These overlapping dyads also echo
this reasoning and explain that “institutional balancing”, often known as the creation or
sponsorship of new forums, is a response to the dominance of stubborn, outdated
multilateral frameworks. Institutional balancing, as He (2015) argued, relies on the use
of international institutions to counter a relationship of more than one power and
constrain their influence.
Reinsberg and Westerwinter (2023) further suggest that the design of frameworks and
institutions with overlapping functions is intentional and the product of powerful countries
aiming to prevent the diminishing of their influence in existing forums. These overlapping
organisational forms provide less powerful or emerging states with a greater range of
institutional options, which is particularly useful in Asia, where there are many competing
institutions vying for the same policy spaces. Hence, Panke and Stapel (2023, p. 10)
found that Asia stands out as a form of “comprehensive overlap” that is rarely nested
based on the percentage of overlapping dyads within the region. Hofmann (2018) states
that these overlapping associations permit states many tactical options, especially
hostage-taking, forum-shopping, and brokering, that have been designed to change the
result of some process. Consequently, forum shopping takes place when a state, facing
opposition in one organisation, seeks out another organisation to which it can present
the same issue, expecting a warmer welcome. By all means, forum shopping is a useful
approach for emerging powers who are attempting to escape structural dependency in
the global hierarchy (Stephen, 2017).
Forum shopping is particularly relevant for emerging powers that try to sidestep
structural dependency in the global order so as to reproduce their preferences across
multiple institutional venues, remould existing coalitions, or abandon unproductive fora.
While forum shopping concentrates on the micro-level tactical behaviour of states,
broader strategic frameworks such as institutional balancing and multi-alignment capture
the rationale behind such decisions. India, for example, can shift between global and
regional forums to reproduce or restructure existing alliances, reproduce their
preferences across institutional venues, or exit unproductive forums. Such behaviour is
