Senior officials from about two dozen of the world's major intelligence agencies held a secret meeting on the fringes of the Shangri-La Dialogue security meeting in Singapore this weekend, five people told Reuters.
Such meetings are organised by the Singapore government and have been discreetly held at a separate venue alongside the security summit for several years, they said. The meetings have not been previously reported.
The U.S. was represented by Director of National Intelligence Avril Haines, the head of her country's intelligence community, while China was among the other countries present, despite the tensions between the two superpowers.
Samant Goel, the head of India's overseas intelligence gathering agency, the Research and Analysis Wing, also attended, an Indian source said.
"The meeting is an important fixture on the international shadow agenda," said one person with knowledge of the discussions. "Given the range of countries involved, it is not a festival of tradecraft, but rather a way of promoting a deeper understanding of intentions and bottom lines.
