>Trump to halt work visas
US President Donald Trump on Monday signed an executive order to suspend the issuance of certain temporary worker visas through the end of 2020, a move critics said would hurt the country's tech industry.
Trump's latest effort to crackdown on immigration follows his measure in April to temporarily suspend immigration to the US, which he said was aimed at protecting American jobs affected by the COVID-19 pandemic.
The new order extends his earlier ban through Dec 30 and expands it by imposing restrictions on a variety of work visas, including the categories H-1B, H-2B, H-4, L-1 and certain J-1 visas.
H-1B visas are designed for highly skilled workers, particularly in the tech industry. H-1B签证是为高技能劳动者设计的，特别是科技行业。
It is the largest visa program of those included in Monday's order.
Trump's order was strongly opposed by those in the tech industry, who said it would harm their efforts to recruit for positions that do not have a strong applicant pool among US citizens.
>Djokovic gets COVID-19
Novak Djokovic tested positive for the coronavirus on Tuesday after taking part in a tennis exhibition series he organized in Serbia and Croatia.
The top-ranked Serb is the fourth player to test positive for the virus after first playing in Belgrade and then again last weekend in Zadar, Croatia.
His wife also tested positive. Djokovic has been criticized for organizing the tournament and bringing in players from other countries amid the coronavirus pandemic.
There were no social distancing measures observed at the matches in either country.
Viktor Troicki said Tuesday he and his pregnant wife have both been diagnosed with the virus, while Grigor Dimitrov, a three-time Grand Slam semifinalist from Bulgaria, said Sunday he tested positive.
Borna Coric played Dimitrov on Saturday in Zadar and said Monday he has also tested positive.
Djokovic apologized to anyone who became infected as a result of the series and said he will be in self-isolation for 14 days.
>Vaccine starts phase 3 trials
The world's first inactivated vaccine developed by a Chinese company to fight the novel coronavirus will carry out its phase-3 clinical trial in the United Arab Emirates.
China National Biotech Group, Sinopharm's vaccine and bioscience unit, held a video conference connecting Beijing, Wuhan and Abu Dhabi on Tuesday for the launch of the trial.
The UAE health ministry granted the approval document for the clinical trial during the video conference.
Since China has few confirmed COVID-19 cases, it could not meet the conditions for the phase-3 trial of the vaccine's safety and efficacy on a large scale, therefore CNBG sought overseas cooperation.
On June 16, CNBG announced the phase-1 and phase-2 clinical trials of its inactivated vaccine had demonstrated good performance in safety and effectiveness on vaccinated volunteers. No subjects showed serious adverse reactions, the company said.
