The Solidarity Center doesn’t have a unique template, and there are many good models across different social movements of successful and lasting transnational solidarity. We have, however, learned a thing or two over two decades as an organisation.
First, transnational solidarity means to be grounded in the idea that we are all equal. Fundamental is that we all have equal rights to dignity, to cultural freedom and sovereignty, and to decent lives as we define them. Equally fundamental is recognising that the forces preventing people from achieving equality and justice are global and affect all of us. The world has not treated us all as equals. The world has treated people very differently based on historic discrimination. People in the Global South have been occupied and exploited by the Global North, and within the Global North we have massive gender discrimination and racial disenfranchisement, among other things. Both points need to be recognised at the same time to have transnational solidarity. You build trust by grappling with all that at once.
Second, relationships are not built on one-off visits. They're built on trust and commitment to each other. You must put in the effort to communicate regularly, to listen. Really listening to counterparts in other countries, who exist within a different social movement context, is not a well-enough developed skill. But you can't be a good ally if you don't develop empathy and love, and that comes, in part, through really listening.
