     The first-ever meeting of G-20 foreign ministers will discuss pressing global issues including  

governance, trans-national crime, green growth, climate change and food security, US officials have 

 said.

     Organised by Mexican Foreign Minister, Ms Patricia Espinosa, in the Mexican resort town of Los

  Cabos, the meeting is to be attended by among others, the US Secretary of State, Ms Hillary Clinton,  

German Foreign Minister, Mr Guido Westerwelle, and European Union foreign policy chief, Ms  

Catherine Ashton.

      Several other G-20 countries including France, China, Brazil and India will be represented at a  lower

level. Mexico is the current chair of the G-20 countries and the meeting will be hosted on June  18-19.

      A senior state department official said that the meeting is informal so it will not result in any formal 

 statements.

      "This meeting reflects, in many ways, the evolution of the G-20 since the first summit (峰会) of  

Washington in the fall of 2008, which was designed to deal with the global financial crisis," the official  

said.

      "This is going to focus on broad non-financial global issues, some of which have been discussed by

  G-20 leaders in the past, but some of which are new to the G-20 process or at least have not been  

emphasized to any great degree, including some broad economic governance issues, some  

environmental issues, development policy, and green growth," the official said.

      During her meetings, Ms Clinton will be emphasizing some themes that are included in the broad

  G-20 rights. Although, she will not be going to get into the details of the G-20 financial part of the

  process, she will call for an open, free, transparent, and fair global economic system.

      Ms Clinton will address things like anti-competitive government practices or interference, which

  include the ways in which governments artificially distort (歪曲) markets or create uneven economic 

 playing fields, the official said.

      Among other things, she will also highlight issues like climate change, freedom of navigation and  

shipping and sailing security to promote a well-functioning global economy; besides governance issues

  like fight against corruption.
