TOKYO/SINGAPORE -- Singapore's Finance Minister Lawrence Wong, heir apparent to Prime Minister Lee Hsien Loong, sought to bolster his international reputation on a 10-day U.S. tour that wrapped up on Monday.
On his first overseas trip since his future post was made known in a leadership transition plan, Wong attended a meeting of Group of 20 finance ministers and central bank governors in Washington, and held a series of high-level meetings.
