Open Skies nations meet over U.S. exit 

Participants in the Open Skies Treaty will hold a conference on July 6 in light of the planned exit of the United States, Russia's RIA news agency cited the foreign ministry as saying last month. 

Last month the U.S. announced its intention to withdraw from the treaty which permits unarmed surveillance flights over member countries, in the Trump administration's latest move to pull the country out of major global agreements. 

In a written statement U.S. Secretary of State Michael Pompeo explained that this decision would take effect in six months after May 22.

Trump meets Mexican president in U.S. 

U.S. President Donald Trump plans to meet with Mexican President Andrés Manuel López Obrador at the White House Wednesday to mark the implementation of the United States-Mexico-Canada Agreement (USMCA). 

It was in April that Lopez Obrador initially floated the idea of meeting the U.S. president. For the Mexican president to make his first foreign trip to see Trump has stirred criticism from both opposition ranks and some of his own supporters. 

Trump, who referred to Mexican migrants as rapists and drug runners in his 2015-16 election campaign and vowed to make Mexico pay for his planned border wall, is held in low public esteem in Mexico, so the visit carries risks for Lopez Obrador. 

Singapore election 

Singaporeans will go to the polls on July 10 in a general election. In a televised address to the nation on June 23, Prime Minister Lee Hsien Loong said he has decided to call the general election now, while the COVID-19 situation is relatively stable, to "clear the decks" and give the new government a fresh, full five-year mandate. 

The election, Singapore's 13th since independence, is likely to again see the People's Action Party (PAP) challenged for all seats – as the ruling party was in 2015. 

A total of 93 elected seats are at stake – in 17 group representation constituencies and 14 single-member constituencies. 

The election will be fought against the backdrop of the COVID-19 outbreak, which has been described as the most dangerous crisis humanity has faced since World War II.
