Tim Cook says Apple is experiencing strong growth in China amid concerns

It appears that Tim Cook has set out to reassure investors that Apple is still seeing strong growth in China, responding to concerns over the company's performance in the country. According to Cook, who sent a letter to CNBC's Joe Cramer, Apple has seen increased iPhone activations in China over the past weeks, as well as improved performance for the App Store.

From Cook's letter, as posted by CNBC's Carl Quintanilla:

Growth in iPhone activations has actually accelerated over the past few weeks, and we have had the best performance of the year for the App Store in china during the last two weeks.

This news comes as stock markets drop across the world, including in China. Apple opened today at $95.17 per share, and as of this writing sits at $102.40, down 3.18% from its close last week.
