**Analysis**
The text is a brief and straightforward statement about a meeting's timing. It doesn't provide any specific context or details about the meeting's purpose or topic. Given this brevity, it's unlikely that the meeting is related to complex or abstract topics like economic development, international trade, or science and technology. It's also unlikely to be related to humanitarian aid or relief, as meetings about aid and relief typically involve specific projects or programs.
