I believe that if this group was created but does not provide significant value, it won't attract many members. You all need to contribute more by sharing an introduction about your company, your strengths, what you need, and in which countries you operate. Additionally, commenting on key global events from the past week or even posting shipping rates for sea and air freight from your country to others can stimulate more interaction.
By the way, I'm from Vietnam and want to connect to all of you !
