(Adds Huawei statement)

May 23 (Reuters) - A Silicon Valley chip startup has accused a top executive of China's Huawei Technologies Co Ltd, Deputy Chairman Eric Xu, of participating in a conspiracy to steal its trade secrets, the Wall Street Journal reported https://www.wsj.com/articles/huawei-executive-is-accused-of-involvement-in-trade-secrets-theft-u-s-startup-said-in-court-filings-11558550468 on Wednesday, citing court documents.

The allegations were made in a lawsuit set for trial on June 3 in federal court in the Eastern District of Texas, in which CNEX Labs Inc claimed that Huawei engaged in a multi-year conspiracy to steal the company's solid-state drive computer storage technology, including with the help of a Chinese university, the WSJ reported.

Huawei said in a statement on Thursday the allegations against Xu were "groundless".

CNEX did not immediately respond to a Reuters' request for comment.

California-based CNEX is developing technology to enhance the performance of solid-state drives in data centers and has been in a dispute with Huawei since 2017.

It had accused Huawei of enlisting a Chinese university professor working on a research project to improperly access the startup's technology.
