In the fourth episode of the Ukraine series Yuliia and Lars Peter take stock of the discussions so far and agree that the two main themes emerging from the conversations are around purpose - the role that humanitarian action plays in Ukraine - and Power - the relationship between and relative power of the national and international actors. To explore these issues, and to round off the series they speak to Frederic Larsson from the NGOResource Center in Ukraine and Ewa Wieliczko the ACAPS team lead in Ukraine.
