Quoted in the SCMP about Secretary Yellen's China visit
“Secretary Yellen is widely respected and is seen as an effective emissary because she focuses on the issues and doesn’t let side problems get in the way of the discussion,” said Cameron Johnson, a Shanghai-based senior partner at consultancy firm Tidalwave Solutions.
Johnson added that trade is “a key driver in the US-China relationship and its ballast” could help reach the goal of maintaining “fairly stable ties” in a US election year, so “it does not affect the outcome of the election”.
