It's hitting the fan. China is homing-up and the US is "posseing" up. CFIUS is expanding its scope and China just required Apple to send its iCloud encryption keys to servers on the mainland. Both moves are more about caution than provocation. The US is stepping up patrols to enforce the trade block on North Korea. China just started the process of amending its Constitution to remove terms limits on its President.
The change to China's Constitution is often mis-portrayed. It affects both the President and Vice President. It does not install a President for life, but simply allows it. More importantly, the Constitution is being updated to include the "Xi Thought", mainly that all ethic groups of China are equal and that helping the entire world is part of China's responsibility.
Many in the West will jump to presume Xi is making a grab for power. While it does increase his power, the more accurate interpretation is that Xi's plans go for the long term, specifically after Trump's term. Without this change, Xi would leave office by 2023. China is thinking in terms of long-term, global strategy. That's hardly a "grab", but more of a "waltz".
This is a significant change. Both the US and China clearly mean business. With a shift toward the long-term, and with China publishing its view that the whole world is part of its responsibility, we are in a different political atmosphere than in years past.
