Lucent ( LU) fired four high-ranking employees in China as part of sweeping corruption investigation into its overseas operations.

Lucent said it removed its president, its COO, a marketing executive and a finance manager from its China unit, according to a filing with the Securities and Exchange Commission Tuesday. The company says the firings stem from incidents and "control deficiencies" that were uncovered during a corruption investigation to make sure the company was in compliance with the Foreign Corrupt Practices Act.

The networking gearmaker started a 23-country cleanup campaign after charges last summer that the company had bribed a Saudi Arabian official to win business.

With the firings in China, Lucent joins newsmaking peers like Nortel ( NT) and Sonus ( SONSE) in having fired or suspended employees after audits and investigations uncovered bookkeeping shenanigans.

Last summer, Lucent caught the eye of federal investigators who are still looking into the company's business operations in Saudi Arabia.

The inquiry follows a lawsuit brought by the National Group for Communications & Computers, which accused Lucent of paying $15 million in bribes to Ali Al-Johani, a former minister of Saudi Arabia's Ministry of Post Telephone and Telegraph. The group charged that Lucent bribed the official in order to win business. Lucent has said it believes the claims are baseless and is cooperating with the Justice Department and the SEC.

As for China, according to the SEC filing Tuesday, Lucent says it "believes the deficiencies and incidents did not have a material impact on its financial results." The company is unable to determine if there will be any future implications on its China business.

Canadian rival Nortel said Monday that the SEC was conducting a formal investigation into the company's books and recent financial restatements. Nortel, which suspended its top two financial executives, has said that the focus of the audits has been on the treatment of accruals or pay installments from sales contracts.

In February, Sonus fired a handful of middle managers after the company's own audit turned up issues of revenue timing. Last month, Sonus asked for extra time to file its annual report.

Lucent shares were largely unchanged Monday. Nortel continued its selloff, dropping 20 cents, or 3%, to $5.86. And Sonus fell 6 cents, or 1%, to $4.02 in midday trading.
