The issue arose after President Samia raised concerns over the announcement, which she said had caught her administration off guard.
While her speech began with familiar remarks on bilateral cooperation between Kenya and Tanzania, it was a brief, unscripted moment, lasting less than 20 seconds, that shifted the tone in the room.
“While we were speaking inside, I pressed Ruto and asked him: you went ahead and announced a refinery in Tanga - why was I not aware? He will explain, himself, why he made that announcement,” she said.
Her comments drew attention to Ruto’s earlier statement made at the Kenya Mining Investment Conference and Expo in Nairobi on April 28, where he publicly referenced plans for the refinery project in Tanga.
The unexpected remarks by Samia introduced a moment of tension at an event that had largely focused on strengthening economic ties and promoting investment opportunities between the two neighbouring countries.
Ruto, who was present at the forum, moved to address the concerns, offering clarification on his earlier comments.
His response sought to reaffirm the importance of consultation and cooperation between the two governments, particularly on projects of such magnitude and regional significance.
The exchange underscored the sensitivity surrounding large-scale infrastructure and energy projects, especially those that involve cross-border collaboration.
It also highlighted the need for coordinated communication between partner states to avoid misunderstandings.
Despite the brief moment of tension, the forum continued with its broader agenda of enhancing trade, investment, and economic cooperation between Kenya and Tanzania.
Leaders and business representatives from both countries reiterated their commitment to deepening bilateral relations and exploring joint development opportunities.
