President Donald Trump said that his historic summit with Kim Jong Un will take place in Singapore on June 12. Here are some relavant facts about the city-state:

1. Until November 2017, Singapore was North Korea’s seventh largest trading partner

In November 2017, the United States imposed North Korea-related sanctions on a number of individuals and companies, including two firms in Singapore. Until that point, Singapore was North Korea’s seventh largest trading partner. In 2015, bilateral trade was worth $29 million. After the sanctions, Singapore’s customs office said that the country will ‘prohibit all commercially traded goods from, or to, the Democratic People’s Republic of Korea (DPRK).’

2. While Singapore doesn’t host any U.S. military bases, the American Air Force and the Navy have had a presence there since 1968

Singapore is at a strategic point in Southeast Asia, lying between Indonesia and Malaysia while serving as a gateway to the Far East. Because of its location, US Navy has had a presence in the country since 1968 to “coordinate maintenance of US Navy ships throughout Southeast Asia.” There’s also a small number of US Air Force staff working at the Paya Lebar Air Base.

3. Singapore’s military has very close ties with the Israeli Defense Force

Singapore has maintained very close military ties with Israel since 1969. The country hosts hundreds of former Israeli military and intelligence officers as well as major Israeli security corporations (such as Israel Aerospace Industries).

In a 2016 visit to Israel, Singapore Prime Minister Lee Hsien Loong remarked how grateful he was for Israel’s support, without which Singapore’s armed forces could not have “grown its capabilities, deterred threats, defended our island, and reassured Singaporeans and investors that Singapore was secure and had a future.”

4. China briefly seized Singaporean military equipment in 2017

Early in 2017, nine Singaporean armored vehicles were seized in transit to Taiwan by Hong Kong authorities. The vehicles, which belonged to the country’s military, were Terrex troop carriers. They were returned — but only after a diplomatic row.

At that time, foreign policy experts suggested that China returned the vehicles as an act of goodwill to mitigate tensions amid rising geopolitical uncertainty caused by the nascent Trump administration.

5. Singapore’s president is a Muslim woman

Earlier this year, Singapore held elections for a new president. The winning candidate was 63-year-old Halimah Yacob, a former speaker of parliament from the Muslim Malay minority. Yacob is the country’s first ethnic Malay president in 47 years – and also the first woman.
