The Pacific Alliance defines itself as a deep integration. However, this feature is not
enough to account for the institutional design and characteristics associated with the
Pacific Alliance. The self-designation of deep integration in the case of the PA may refer
to questions of rhetoric or the desired destination towards which this integrationist
initiative will lead in the future, but it is not a feature of its current institutional structure.
On the other hand, the lack of consensus on the meaning and characteristics of deep
integration should be pointed out. A number of authors, such as Schiff and Winters
(2004), Barbosa and Buitrago (2019) consider that a fundamental condition for deep
integration is supranationality, which allows, through the transfer of sovereignty, the
harmonization of macroeconomic policies. On the other hand, another group of authors
do not consider supranationality as an unrestricted condition for the achievement of deep
integration. In that sense, for Vásquez (2013) this type of integration seeks to materialize
global reforms within economies through openness, policy homologation and promotion
of interdependence. This type of integration is based on four pillars: i) reduced
differences in standards and production systems; ii) stability of governmental
mechanisms; iii) eradication of custom and non-custom barriers; iv) elimination of
barriers to trade in services (2013, p. 73). For Briceño, Legler and Prado (2022),
interpreting the declarations and other documents of the Pacific Alliance, indicate that
deep integration can be understood as a free trade zone that allows the free circulation
of factors, but does not establish a common external duty or a joint trade policy. (2022).
The type of integration and regionalism, characteristic of the Pacific Alliance, has been
considered from different shores. For example, Rojas and Terán classify it as New Latin
American Regionalism (2016) this theoretical proposal of these authors, which goes
beyond the exclusively commercial dimension and is framed in the new global and
regional dynamics. Ardila (2015), on the other hand, calls it the New Latin American
multilateralism (2015) and for Garzón (2015), it consists of Cross Regionalism (2015)
because it consists on a complex network of trade agreements even with extra-regional
economies and provides benefits such as: exercising a greater degree of control over the
liberalization, increasing the attractiveness of foreign direct investment by signing trans-
regional agreements with many extra-regional partners; and allowing economic visibility
by establishing themselves as FTA "hubs" and serving as bridges between different
regions" (Garzón, 2015, p. 11).
Another characteristic feature of the PA's institutional structure is its leadership. In this
integration scheme, there is no evidence of a vertical and hierarchical structure led by a
member state. In this sense, it can be considered that there is a shared leadership based
on the Pro-tempore Secretariat, with an annual rotation among each member. In the
words of Malamud (2011, p. 224), the PA is a liberal intergovernmentalism type: "it
conceives regional integration as the result of the sovereign decision of a group of
neighboring states [...] these states promote international cooperation to satisfy the
demands of their relevant national actors. The intended outcome is the strengthening of
state power, which retains the option to withdraw from the association, rather than its
dilution into a regional entity" (Malamud, 2011, p. 224). Therefore, it is also of a
presidentialism type, since the deliberative space where the transcendental decisions are
taken are the presidential summits (González, 2021). The main mechanism for decision-
