Item 1.	Security and Issuer
This Amendment No. 4 to Schedule 13D amends and supplements the Schedule 13D filed with the Securities and Exchange Commission (“SEC”) on August 27, 1999 as amended and supplemented by Amendment Nos. 1, 2 and 3 filed with the SEC on December 28, 1999, July 24, 2001 and May 29, 2003, respectively. The class of securities to which this Schedule 13D relates is the ordinary shares, par value $.01 per share (the “Ordinary Shares”), of EURO TECH HOLDINGS COMPANY LIMITED, a British Virgin Islands corporation (the “Issuer”). The principal executive offices of the Issuer are located at 18/F Gee Chang Hong Centre, 65 Wong Chuk Hong Road, Hong Kong.
Item 2.	Identity and Background
This statement is being filed by a group consisting of T.C. Leung, Pearl Venture Ltd. (“Pearl”) and Regent Earning Ltd. (“Regent”) (the “Reporting Group”). Pearl is a British Virgin Islands corporation which is a trust for the benefit of Mr. Leung. Regent is a Hong Kong corporation of which Pearl is the majority shareholder.  Mr. Leung is Chairman of the Board and Chief Executive Officer of the Issuer. The respective business addresses of the members of the Reporting Group are as follows:

Name	Address
T.C. Leung	c/o Euro Tech Holdings Company Limited
	18/F Gee Change Hong Centre
	65 Wong Chuk Hang Road
	Hong Kong
Pearl Venture Ltd.	Columbus Centre Building
	Wickhams Cay
	Road Town, Tortola,
	British Virgin Islands
Regent Earning Ltd.	20/F, Yue Shing
	Commercial Building
	15-16 Queen Victoria Street
	Central, Hong Kong

During the past five years, no member of the Reporting Group (including the officers and directors of Pearl and Regent) has been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result thereof was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Mr. Leung is a citizen of Hong Kong. Pearl is a British Virgin Islands corporation. Regent is a Hong Kong corporation.

Item 3.	Source and Amount of Funds or Other Consideration
Prior to the Reporting Event (described below), Mr. Leung directly owned 366,676 Ordinary Shares of the Issuer.  As a result of the Reporting Event, Mr. Leung directly owned 566,430 Ordinary Shares.  Mr. Leung possesses options to purchase the number of Issuer’s ordinary shares as indicated pursuant to the following plans and at the prices indicated opposite the plan names:.

			Exercise Price
Plans	Number of Shares		(US$)
Management Options	2,457,000		1.6789
	1,146,600		1.221
2000 and 2002 Officers’	(a)	567,000	0.5857
and Directors’ Plans	(b)	66,000	0.5787
	(c)	205,800	0.8191
		4,442,400

The Issuer’s 2000 and 2002 Officers and Directors Plans both contain “cashless” exercise provisions permitting the optionholder to pay for the exercise of his option by surrendering Ordinary Shares valued at the fair market value of such shares on the date of exercise, provided that such shares were held by the optionholder for not less than six months prior to the date of exercise of the option.

Mr. Leung has exercised 234,300 options exercisable at $0.5787 per share granted to him pursuant to the 2000 Officers and Directors Plan of the Issuer by the payment of $30.91 in cash and the surrender of 34,546 Ordinary Shares owned by him valued at $3.924 per share (or $135,558.50), for an aggregate exercise price of $135,589.41.  As a consequence, Mr. Leung’s ownership changed by cancelling 34,546 shares, but with the Issuer, issuing to him 234,300 new shares, for a net increase of 199,754 shares (the “Reporting Event”).  The shares owned directly by Mr. Leung increased from 366,676 shares to 566,430 shares.  His options decreased by 234,300 from 4,676,700 options to 4,442,400 options.

Item 4.	Purpose of Transaction
Investment purposes.

Item 5.	Interest in Securities of the Issuer
As of the date hereof, the aggregate number of shares held of record by all members of the Reporting Group is 8,047,903 or approximately 72.2% of the Issuer’s issued and outstanding Ordinary Shares. Mr. Leung possesses sole voting and dispositive power as to 566,430 of the Issuer’s Ordinary Shares owned by him and as to the options to purchase 4,442,400 of the Issuer’s Ordinary Shares. Regent and Pearl share voting and dispositive power as to the Ordinary Shares owned of record by Regent (265,082 shares or 4.0% of the Issuer’s Ordinary Shares). When Pearl’s record ownership (2,773,991 shares) is aggregated with its beneficial ownership in the shares held in the name of Regent, Pearl beneficially owns 3,039,073 shares or 55.4% of Issuer’s Ordinary Shares.

None.
