The case of Justin Sun’s lunch with Warren Buffett is becoming curiouser and curiouser.

First, Sun sent out a tweet canceling his lunch. A tweet from the TRON foundation, which governs the Tron cryptocurrency peddled by Sun, followed soon after, stating that the lunch had been postponed by mutual consent.

Then a Chinese publication reported that Sun could not leave the country because he was facing legal problems in China. The publication alleges that Sun’s Tron network was involved in money laundering and gambling. His other company – Peiwo – that developed mobile apps has been charged of spreading pornography through its apps by Xinhua, China’s national news agency.

Sun denied that he was facing problems and posted a Periscope video showing himself in San Francisco. Sources for The Block have told the publication that Sun is indeed in San Francisco but is subject to border control restrictions back home, meaning he will not be able to leave China if he returns there. According to the publication, Sun has decided to “stay low-key by not attending the lunch with Buffett.”

At $4.57 million, the lunch was already an expensive affair. Subsequent events have proved it to be even more pricy for Sun.
