A U.S. official cautioned Israel on Wednesday over investments from China, citing cyber-security concerns and the prospect of Israel's allies limiting intelligence-sharing with it.
The Trump administration has taken steps to curb market penetration by Huwaei Technologies Cos Ltd and ZTE Corp, two of China's biggest network equipment makers, seeing them as spying threats. Both firms deny having any such purpose.
Interest by Huwaei and ZTE in Israel has worried its U.S. ally, as has the green light it granted China's Shanghai International Port Group in 2013 to build a private port near Haifa, a berth for the U.S. Mediterranean fleet.
"We know that the threat of cyber attacks is growing each and every day," U.S. Deputy Secretary of Energy Dan Brouillette said in a statement to Reuters during a visit to Israel.
He said that in his meetings with Israeli officials, he would "share our experiences and concerns regarding certain Chinese foreign investment in Israel, and hope to continue a dialogue on best practices".
One of Brouillette's hosts, Israeli Energy Minister Yuval Steinitz, said in a statement after their meeting that the U.S. deputy secretary had "raised their concern about the issue of foreign investments in the State of Israel".
There was no immediate Israeli comment on Chinese investment, however.
Asked separately about Chinese investment in Israel, Brouillette said in remarks aired by Israeli Army Radio: "If done incorrectly, you inhibit the other allies from sharing intelligence with you."
In a possible sign of U.S. displeasure at the Chinese involvement in Haifa, one of the Sixth Fleet's warships in October docked in Israel's second-tier Mediterranean port of Ashdod, the fleet's first such visit in almost 20 years.
In December 2016 Huawei acquired Israel's HexaTier, whose technology secures databases in the cloud, for $42 million. This followed a visit to Israel by the Chinese technology giant's CEO. That same month, it also acquired IT research firm Toga Networks for an undisclosed amount.
According to Israeli media, ZTE has shown interest in Israel's tech sector since sending a senior delegation to the country in 2013.
Haaretz reported in 2016 that Israel has an undeclared policy of not using Huwaei or ZTE technologies, out of concern about possible security breaches. Israeli authorities have not commented on that report.
