I'll let others post about the PM's planned appearance.  I haven't checked, but I bet there are some. Or soon will be.

Another sentence caught my eye: "Angelina Jolie and author Loung Ung will be discussing their upcoming film First They Killed My Father ..."  

Well, the cynical amongst us would likely agree, a good PR/promotional opportunity is where you find it. 
1. The book is not new (it's 17 years old)
2. Its author is not Canadian 
3. Its author is not a woman's right activist, she's a human-rights activist. 
4. The memoir (and quite likely, the movie) has nothing to do with women's struggles--but rather, civil war in Cambodia. 
5. That means the Khmer Rouge events within book/movie are now half a century old. Historical, now. Not current.
6. Possible connections to women who live in "the country that currently leads the world in its commitment to progressive ideas and action," are not explained. 
7. However, Jolie's movie is brand-spanking new. 

For the cynical, enough said.
