Tesla (NASDAQ:TSLA) will report its fourth-quarter results next week. With the stock trading at all-time highs, the report will undoubtedly be subject to scrutiny. One of the key areas for investors to watch will be Tesla's comments in its quarterly letter to shareholders and the earnings call regarding its plans in China.

While this almost certainly won't be the case in 2014, it's clear that Tesla is already taking the market seriously. Tesla vice president of China operations Veronica Wu recently said that the company is aiming for its China unit to contribute about one-third of Tesla's global sales in 2014.
