According to the city-state`s Ministry of Foreign Affairs, the United Kingdom`s Queen Elizabeth II noted that Lee`s life has been inextricably interwoven with the history and development of Singapore.
"It is notable that this year also marks the 50th anniversary of Singapore`s independence from the UK and I am delighted that the links between our countries remain so strong," she added.
Germany`s Chancellor Angela Merkel also sent her greetings. She said for over 50 years, Lee has been "a decisive figure" helping to shape Singapore`s destiny and leading the country to peace and prosperity.
"It is in no small measure thanks to your prudent policymaking that the regional association ASEAN has become a force for reconciliation and stability in Asia," local media quoted Merkel as saying.
She recalled the "stimulating conversation" she had with Lee during a meeting in 2011 when she visited Singapore. She also said Singapore will remain "a key partner" for Germany in Asia.
