At least two of several agreements aimed at ending global conflicts that US President Donald Trump has hailed as evidence of his negotiating prowess are in trouble and at risk of collapsing. Less than a week after Congo and Rwanda signed a deal in Trump’s presence in Washington that was meant to halt fighting in eastern Congo, and less than two months after he witnessed Cambodia and Thailand sign a ceasefire pact in Malaysia to end their border conflict, fighting has surged in both places.

The developments have caused international alarm, which on Tuesday resulted in urgent calls to halt the renewed violence from countries involved in the African Great Lakes region and from US Secretary of State Marco Rubio. In each case, the statements urged the combatants to live up to their commitments in the deals that Trump has touted in part as the rationale for casting himself as the “president of peace”.
