Secretary of State Rex Tillerson has often been the silent man in the Trump foreign policy team. But out of the spotlight, he appears to be crafting a broad strategy aimed at working with China to resolve the North Korea crisis and with Russia to stabilize Syria and Ukraine.

The Tillerson approach focuses on personal diplomacy, in direct contacts with Chinese and Russian leaders, and through private channels to North Korea. His core strategic assumption is that if the United States can subtly manage its relations with Chinese President Xi Jinping and Russian President Vladimir Putin — and allow those leaders to take credit for successes — complex regional problems can be solved effectively.

Tillerson appears unfazed by criticism that he has been a poor communicator and by recent talk of discord with President Trump. His attitude isn’t exactly “take this job and shove it,” but as a former ExxonMobil chief executive, he doesn’t need to make money or Washington friends — and he clearly thinks he has more urgent obligations than dealing with the press.
