The creation of working groups between the US and China can only be viewed as a positive policy following the unsustainable pace of reciprocal countermeasures the two states have imposed upon one another in recent times. Given the need for clarity between China and the US, the attempted use of dialogue is relief amid the growing threat of confrontation.
So far, despite enhanced dialogue, meetings between the US and China have rewarded little material gain for the world. China continues to evade the US' concerns over its behavior, and Washington skips around topics that may anger Beijing. Time and time again, it has been proven that, despite best intentions, dialogue between international powers simply isn't enough.
There's a 20% chance of a US-China war before 2035, according to the Metaculus prediction community.
