A veritable parade of overseas CEOs including Tesla's Elon Musk and Goldman Sachs' David Solomon have made their way to a reopened China in the last few months.

One notable common strand: they've not talked much in public about their trips which have mostly consisted of meetings with government officials, local staff and business partners. Media events and other public engagements, once frequent before the pandemic, are now rare.

Even Musk, known for his unreserved banter on Twitter, was uncharacteristically silent on a whirlwind trip last week.
