China contributed 22.99 percent of 's revenue in the second quarter, up from 20.97 percent in the first quarter and up from 22.36 percent in the same period last year.

Tesla (NASDAQ: TSLA) saw its revenue from China rise sharply in the second quarter compared to the same period last year, but there's a catch.

In the second quarter, Tesla's revenue from China was $5.731 billion, up 51.33 percent from the same period last year and up 17.17 percent from the first quarter, according to a 10-Q filing it filed with the SEC today.

Tesla didn't specify, though that year-on-year surge was largely due to a low base for its deliveries in China in the same period last year because of the Covid disruption.

Tesla's Shanghai factory was shut down for about a month at the end of March last year due to the city's Covid lockdown, and production didn't begin to gradually resume until April 19 last year.

This resulted in Tesla delivering 89,275 vehicles in China in the second quarter of last year, including just 1,152 in April, data from the China Passenger Car Association (CPCA) monitored by CnEVPost showed.

The US EV maker's total revenue in the global market in the second quarter was $24.927 billion, up 47.2 percent year-on-year and up 6.85 percent from the first quarter, according to its financial report released earlier this month.

The US market contributed $11.332 billion, or 45.46 percent, to Tesla's total revenue in the second quarter.
