Dear Delegates,

Welcome to CancunMUN 2024!

My name is Lilly Kruitbosch, and this year I am delighted to be the Chair of the Security Council in CancunMUN 2024. I am 17 years old and a senior at the International American School of Cancun. Before joining IAS, I went to school in California, Qatar, and Switzerland, where I was born. When I am not in school I enjoy being with my friends and family, playing sports, singing, painting, and visiting new places. After I graduate high school in 2025, I want to study medicine in the Netherlands. 

This will be my fourth MUN conference. The first conference I attended was two years ago at CancunMUN. I was a delegate in WHO and won an honorable mention for best delegate. I also attended RIMUN in Rome, Italy. Last year I was honored to be Chair of the General Assembly and had a wonderful committee and I can’t wait to make this committee even better. It was two years ago when I first encountered MUN and gained an understanding of what it entails. The more I learned about it the more I wanted to be a part of it. I am so passionate about MUN because it helped me grow in confidence and how to work together as a team. 

I am so privileged to be your chair in SC. I am looking for my delegates to be confident, prepared, professional, respectful, focused, hard working, and most importantly I want you to try your best and challenge yourself to grow. I want you to leave the conference with more confidence so you can look back and be proud of what you have done. I can not wait to see this committee be the best committee but we can only have that with rich and strong debates and outstanding delegates like you. I want you to be reminded that the background guide should not be your only source of information; you should use sources that are reliable.


If you are stuck or need help with anything, feel free to reach out to me at and I will be glad to help you.

I am looking forward to this amazing conference and seeing you soon!


Lilly Kruitbosch, Chair 

Security Council 



Fellow Delegates,

My name is Ania Arjona and I’m enthusiastic about being co-chair of the Security Council this year. I am a junior at International American School of Cancun, and I am 16 years old. In my free time I like to read, bake, and hangout with friends. I’m not yet sure of what my future will look like because I have a lot of passions, but it has always been my dream to study astronomy/astrophysics or law.

This will be my 4th MUN conference. The first time I participated in MUN I was in UNICEF, where I won Honorific Mention for Best Delegate. My second time was in the Security Council, where I won Best Position Paper. And lastly my third time was in RIMUN (Italy) Participating in MUN as a delegate has encouraged me to challenge myself to be a chair of the Security Council this year. 

I am eager to be your Chair this year, but I do expect that all my delegates come not only prepared and confident, but also excited. But remember that this is not only a fun experience, it is also a serious role to take on. Security Council is one of the most challenging committees of the UN, and this is why I expect you to do your best so we can have an outstanding and rich debate. Make sure to use the resources we have provided and use reliable sources. Additionally, please be respectful;  discourtesy will not be tolerated. 

With that being said, if you have any concerns or questions please feel free to contact me at

I look forward to meeting you at the Security Council this year. Good Luck Delegates!

Ania Arjona, Co-Chair
