Yellen says U.S.-China ties are “firmly anchored” after the trip

US Treasury Secretary Janet Yellen struck a positive but pragmatic tone after completing a high-stakes trip to China aimed at reassuring officials that the US will not hold back its biggest economic rival.

Yellen’s comments were delivered at a press conference capping a four-day visit to Beijing that she had described as a mission to revive engagement between the two largest economies. Frictions between Washington and Beijing have spilled over into a trade war that has seen both sides curb exports vital to advanced technologies.
