Note: Since this is a government-oriented meeting to determine the team working progress and hear about challenges and highlights, priority of asking questions and providing comments will be given to program managers and government participants. Other participants might submit questions and they will be answered if there is time available. The team might follow it up after the meeting to answer those questions.
