international  legal  assistance,  creation  of  joint 
investigative  teams,  etc.);  effective  interaction 
with competent bodies of foreign countries and 
international  organizations  (Ortynskyi  et  al., 
2018). 
 
At the same time, the establishment of effective 
cooperation between the authorized bodies of the 
states involved in such activities, is among the 
important  conditions  for  success  in  the 
investigation of transnational organized crime. 
 
In the context of our research, it should be noted 
that the organization of international cooperation 
is  an  integral  component  in  the  activity  of 
investigating  transnational  organized  crime, 
taking  into  account  its complex  nature.  At the 
same time, one can find content-like concepts in 
normative  legal  acts  and  legal  literature: 
"international cooperation",  "international  legal 
assistance", "mutual legal assistance", etc.  
 
In accordance with Clause 1, Part 1, Art. 541 of 
the  Criminal  Procedure  Code  of  Ukraine, 
"international legal assistance" is the conduct of 
proceedings by the competent authorities of one 
State, the performance of which is necessary for 
pre-trial  investigation,  trial  or  for  the  sentence 
imposed  by  a  court  of  another  State  or  an 
international judicial institution. 
 
Instead,  international  cooperation  means 
purposeful and permanent, joint and coordinated, 
broad  in  scope  and  diverse  in  forms  and 
directions,  organizational  and  legal, 
investigative, informational in nature, aimed at 
achieving the tasks set before law enforcement 
agencies (Zharovska, 2014). 
 
In view of the above, we believe that the concept 
of international cooperation covers a much wider 
range of interactions between authorized bodies 
of different States in their joint efforts to combat 
crime  through  international  organizations 
collaboration,  intergovernmental  institutions, 
state  authorities  and  local  self-government, 
judicial  and  law  enforcement  agencies,  public 
associations  and  organizations,  individual 
citizens, the main purpose of which is to detect, 
investigate,  and  prevent  the  commission  of 
criminal  offenses,  finding  ways  to  combat 
criminal manifestations. 
 
In  view  of  the  above,  in  order  to  reveal  the 
subject matter of the research, in particular in the 
context  of  the  investigation  of  transnational 
organized crime, we will consider the concept of 
"international  cooperation  in  criminal 
proceedings" in the context of the joint activity 
of the authorized bodies of the central executive 
power  with  judicial  and  law  enforcement 
agencies,  which  lies  in  providing  international 
mutual legal assistance in criminal proceedings 
during  the  collection  of  evidence,  conducting 
procedural actions, handing over documents, etc. 
 
We agree with the view of Zavydnyak (2021b), 
that  it  is  impossible  to  ensure  collection  of 
evidence  abroad;  prosecution;  protection  of 
human  and  citizen  rights  and  freedoms  in 
criminal  proceedings;  compensation  for 
damages,  as  well  as  possible  confiscation  of 
property  without  proper  organization  of 
international  cooperation  in  proceedings 
regarding crimes of a transnational nature. 
 
The issue of international cooperation of pre-trial 
investigation  bodies  with  similar  bodies  of 
foreign States has recently become very relevant, 
since  the  full  implementation  of  criminal 
proceedings, in this case, most often depends on 
their  cooperation.  Thus,  it  is  possible  to 
distinguish  two  directions  of  international 
cooperation of law enforcement agencies in the 
fight  against  transnational  organized  crime. 
Firstly,  international  cooperation  providing 
operational  police  assistance  pending  official 
request  without  reference  to  treaties  on  legal 
assistance.  Such  direct  contacts  between 
investigators  are  discouraged  or  even  not 
allowed,  but  they  allow  direct  communication 
with  colleagues  involved  in  specific  criminal 
proceedings.  These  contacts  provide  an 
opportunity  to  quickly  receive  information  on 
requests in real time and help the investigator to 
establish  the  presence  of  certain  facts  before 
seeking  official  access  to  evidence  through 
«application  letters».  It  should  be  noted  that 
direct  communication  without  reference  to 
international instruments violates the assistance 
procedure. At the same time, such deviation is 
permitted  in  exceptional cases where there  are 
serious risks: threats to the life and health of the 
injured person or his family; irreversible loss of 
very  important  information,  as  well  as  real 
grounds  for  the  suspect  to  abscond  or  his 
subsequent identification will be impossible. In 
such  cases,  information  is  provided  to  the 
employee  of  the  Interpol  National  Central 
Bureau  indicating  the  specific  grounds  for 
conducting  investigative  actions  without 
reference to international treaties; all necessary 
«application letters» are processed in  the usual 
way. Secondly, international cooperation based 
on formal «letters of application» filed after the 
opening  of  criminal  proceedings  or  formal 
investigations; in this case, the issues of issuing 
an  arrest  warrant,  ensuring  the  right  of  the
