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-
