I have used this list of 25 Openness questions with various groups, both abroad, as well as on my home campus.  

In Peru, these questions were used to connect my US study abroad group with their local counterparts.  On campus, domestic students used were given this list and tasked with conducting an informal "interview" with someone different than them.  The first time I gave this assignment, I brought in a group of international students.  The second time, I directed my students to seek out an international student whom they've met, but wish to get to know better.  The third time, I left "different" open to their interpretation.  This allowed for more flexibility and resulted in diverse examples of difference.  

I'd suggest this list be used loosely; allowing students to pick and choose what to ask/respond to.  If the conversation turns into a formal interview, the true objective - making a personal connection - may be lost.   

This might be a good way for pairs or small groups to get to know each other in a COIL/international virtual education experience. I would encourage the use of synchronous meeting platforms so students can talk through their responses with each other. Note that there is the original version with 25 questions and a "mini" activity with only 5, so you have some options in terms of how much time you want to devote to the activity. If asynchronous communication is your only option, consider choosing 1-2 questions a week to jumpstart other discussions, so that group relationships deepen over time.
